Refactor

[EloiMarin]

Use refactored ofxTableGestures

• Update all graphics to use the new subsystem (shaders and FBO hardware support needed).
• Log level restored to default.
• Use whatever window manager OpenFrameworks wants ot use (mainly GLFW).

Code cleaning

• Restructure and rename (for consistency) some source files.
• Let clients compute and draw object distances (they have enough data to do it).

WARNING: All the work was done offline. Most likely the project won't compile in between partial-commits, that I made just to show the work done in a more structured way.
(Sorry for any inconvenience)
