-project settings are saved when changed

-load() was in the GDScript docs but missing in the scripting-different music for platformer 2D and 3D
-fix how documentation is generated, built in doc browser should be always up to date
-copypaste, scrolling, etc in  builtin doc
-built-in scripts get saved now (though debugger may not always work on them)
-Theme can be set to controls as a property

+Godot Author's Own Collada Exporter
+-----------------------------------
+
+1) Copy the "io_scene_dae" directory  to wherever blender stores the 
+   scripts/addons folder (You will see many other io_scene_blahblah like
+   folders). Copy the entire dir, not just the contents, make it just like
+   the others.
+2) Go to Blender settings and enable the "Khronos Collada" plugin
+3) Enjoy proper Collada export.
+4) If it's broken, you can:
+   a) Flame the Blender developers in their mailing list for changing 
+      the API every month.
+   b) Flame the Blender developers for not giving a home to this script
+      and mantaining it themselves, instead choosing to use the huge,
+      bloated and buggy OpenCollada based implementation that is as big 
+      as Blender itself, while this script is a little over 1000 lines 
+      of code, works better and has more features.
+   c) Cry to the poor Godot developers who are busy enough to fix it,
+      because they are good people and will fix it for you anyway (submit 
+      an issue to github).
+   d) Be a Hero, save the day, fix it yourself and submit a pull request to
+      github with the changes.
