If we update build gradle to use ``compileSdkVersion 23``,
``org.apache.http`` package causes error. (issue #4711)
We need to use ``useLibrary 'org.apache.http.legacy'`` to solve this problem.
To use ``useLibrary``, we need to use latest gradle also.
And now, we faced another problem with ``APK Expansion`` java sources.
```
/platform/android/java/src/com/google/android/vending/expansion/downloader/impl/DownloadNotification.java
137 : mCurrentNotification.setLatestEventInfo(mContext, mCurrentTitle, mCurrentText, mContentIntent); // causes error
```
So, some of APK Expansion java sources are updated by referencing commits from https://github.com/danikula/Google-Play-Expansion-File
And dropped V3CustomNotification.java which was for android 3.0, since godot supports android 14 (4.0) above officially.
Unfortunately, another problem, The 'MissingTranslation' error was occurred.
So, build.gradle is updated to use ``disable 'MissingTranslation'``
Additionally, I updated ``buildToolsVersion``, ``targetSdkVersion`` to latest version.
I tested APK Expansion funtionality on Android 6.0 (Nexus 9, Nexus 6p) and Android 4.4 (Galaxy Note 2) with Google Developer console.
add version_info and icon sections in "export to windows platform".
add version_info and icon to godot exe file (editor & template exe).
fix an problem in image class.
change all default icons to android export icon (a little more rounded).
create an python script for convert file to cpp byte array for use in
'splash.h'.
