changing 3DModelLoader addon to work with OpenGL ES
adding Android example for ofx3DModelLoader
working version
updated FreeImage version, fixes #1028
ofEvent: fix for void events. Closes #1166
Merge branch 'develop' into feature-android3DModelBuilder
1. Made getRealExternalStorageDirectory static and public.
This way you can use this method in your application as well if needed.

2. Changed the dataPath location to the proper storage location.
According to the official developer guide, files written to the external storage should be placed in: /Android/data/<package_name>

More information can be found in the Android guide: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal section Accessing files on external storage

This will also help to keep the SDcard clean and prevents assets from being indexed as /Android/data usually contains a .nomedia file.
Fixed AndroidVideoGrabber streaming
- Added OF functions that wrap glLoadMatrix, glMultMatrix and glLoadIdentity so that these get passed on the the renderer.

- Lessened the need for GLU in ofGLRenderer by replacing gluLookAt and gluPerspective with ofMatrix4x4 functions. There is still a gluProject call in there, after that ofGLRenderer does not need GLU.
- Changed ofLoadMatrix and ofMultMatrix to use references.
- ofGLRenderer no longer calls ofMultmatrix or ofLoadMatrix, but rather it's own internal functions.
- Replaced a gluPerspective on ofCamera with code using a ofMatrix4x4.
- Replaced a few glMultMatrixf with ofMultMatrix calls.
Added multMatrix, loadMatrix and loadIdentityMatrix to ofRendererCollection
Rename 'IOS Testing' to remove the space

This was the only path with a space, and the code styler does not handle space in paths yet.
Disable option adding license header to OF core files.
Add first version of script for styling all of OF. 

Style all of OF when called, no automated call capabilities yet (i.e. logging, return values, error handling).
Remove old entries from addons/.gitignore
Ignore .log files in code styler.
Adjust style config to fix newlines in else statements.
Update Readme with uncrustify minimum version 0.58. Correct typo in script output.
Re-enable license header for OF core. Remove copyright notice from header.
fix - ofMesh.load() resolves an issue where Normals would not be loaded back in.

When saving a .ply file using ofMesh::save() normals are stored as vertex element properties. These were, however, not imported in back again in ofMesh.load() because ofMesh.load() expected normals to be in an element list.

This fix brings ofMesh::load() in line with ofMesh::save() and the .ply file format specs by loading normals as vertex element attributes if normals are declared in the .ply.
