changing 3DModelLoader addon to work with OpenGL ES
adding Android example for ofx3DModelLoader
updated FreeImage version, fixes #1028
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.
Add ofCurveVertex(x, y, z) overload

For consistency with ofVertex and ofBezierVertex
ofxSVG: set winding mode to non-zero (the default for svg)
ofxSvg: fixed capitalization of file names
ofxSvg: fix copy semantics, using internal pointers makes a copy of an ofxSvg a swallow copy
ofxSvg: remove dependencies with tinyxml
ofxSvg: use ofLog
svgExample: remove ofxXmlSettings, not needed
svgExample: create outlines in setup with correct winding
changed to GL_NEAREST filtering to stop values bleeding from linear interpolation
changed to using texture coordinates instead of vertex position as it can be passed directly without any arithmetic to change from screen space to texture space
changed to simpler draw routine for updating position and velocity pingPongBuffers, also fixes a strange bug where the last particle overlaps position with another causing one extra bright particle
fix issue 532 ofEasyCam setPosition doesn't work as ofCamera's does, fix issue 1718 ofEasyCam can't move if the distance to target equals 0
cleaned up ofxAssimpMeshHelper
added ofxAssimpAnimation which acts a lot like a video player for 3d models and wraps aiAnimation object.
moved all animation code from ofxAssimpModelLoader to ofxAssimpAnimation.
