Also fixes two [-Wunused-value] warnings:

```
Some of those are bugs and need further work, they are identified with
`// FIXME` comments.
We're not formally using C++11 yet so those trigger compilation warnings
(at least with GCC 5):
./main/input_default.h:122:30: warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11
CursorShape default_shape = CURSOR_ARROW;
^
Note: We may allow those eventually (especially for non-int static const),
but most of current occurrences were inconsistent with all other classes.
See also http://www.stroustrup.com/C++11FAQ.html#member-init
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
- Add pressed state to clear button
- Enable clear button on all inputs with search icon
- Remove duplicate clear buttons
- Fix rendering of icon for center and right alignments
- Add clear button to more search fields
- Add clear icon to default theme
- Add method to control enabled state of clear button
- Add property to enable clear button from inspector
* Prototype faster function call ux.
* Work on general search ux.
* Able to create nodes from search.
* Show class for variables but not methods.
* Get actions search working.
* Descriptions now show for both methods and properties.
* Enable zooming on mouse wheel up and down.
* Make the drag trigger on right mouse button.
* Search now shows for action visual script nodes.
* Able to search visual node names.
* Search works better.
* Change zooming scale to hide artifacts better.
* Remove zoom changes
* Select from base should check properties too like the other functions.
* Seq_connect flag is needed to set sequence lines correctly.
* Remove comment
* Code cleanup with function names and arguments.
* Use brief description for search descriptions.
* Clean and fix bug with input nodes connecting with sequence lines.
* Add a warning and fix some edge conditions with sequence into data lines and vice versa.
* Don't search functions when pulling from a sequence node.
* Don't show actions when pulling from a data line.
* Set set and get properties.

* Add bigger hit zones to node connect.
* For the drop zones, make all the rect2 areas the same size.
* Function names in visual script node should be lower case so that search works better.
* Use the convention of capitalize() for set, set, visual script nodes and methods.
* Make search more general. Ignore "_" and make case-insensitive. Also made the search window smaller and remove extra info from search
* Make type_cast use the connecting node's type and remove use of found variable.
* Fix case where you call an instance's call function where it becomes an invalid call.
* Make get_visual_node_names use a set of filters, move action creations and fix bug with sequence node connections.
* Make the window bigger.
* Make connect_data and connect_seq more robust.

* Pass the type in a VisualScriptFunctionCall too.
* Set the base type correctly in VisualScriptFunctionGet and VisualScriptFunctionSet using hint string.
* Make sure the instance is passed in VisualScriptPropertySet.

* Extract hot zones into a function.
* Move hot_zones constants into default theme.
* Bigger capture zones.
* Clean messy port_grab_distance variables.
* Remove RMB functionality.
* Remove memory leak on showing visual script descriptions.
* Read the port_grab_distance constants on enter tree and theme changed.
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
This makes a VisualScriptEditor singleton, which gives plugins the
ability to register their own custom nodes. Those will be available for
insertion in the Visual Script editor, under the "Custom Nodes"
category.
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
It is explained in this article: https://www.viva64.com/en/b/0226/
