Allow ++ as an alternative separator to -- for user CLI arguments

Browse source 
This is required when using `startx` to start a Godot project, as
`--` is used by `startx` for its own arguments (and there is no way
to escape it).

<method name="get_cmdline_user_args">
<return type="PackedStringArray" />
<description>
Similar to [method get_cmdline_args], but this returns the user arguments (any argument passed after the double dash [code]--[/code] argument). These are left untouched by Godot for the user.
Similar to [method get_cmdline_args], but this returns the user arguments (any argument passed after the double dash [code]--[/code] or double plus [code]++[/code] argument). These are left untouched by Godot for the user. [code]++[/code] can be used in situations where [code]--[/code] is intercepted by another program (such as [code]startx[/code]).
For example, in the command line below, [code]--fullscreen[/code] will not be returned in [method get_cmdline_user_args] and [code]--level 1[/code] will only be returned in [method get_cmdline_user_args]:
[codeblock]
godot --fullscreen -- --level 1
# Or:
godot --fullscreen ++ --level 1
[/codeblock]
