logo change

This release has the following content:
 1) logo changed from "qtamoVR" to "meshpage.org's GameApi Builder" with colourful letters.
 2) lod support has the following fixes:
      a) vox_lod implements lod for voxels
      b) coordinate system for lod instancing was improved significantly/now its consistent with rest of the library
 3) instanced rendering is now more dynamic. The NumOfItems() and MaxNumOfItems() variables were separated to
     allow dynamic changes to the numofitems variable. The buffer sizes use more stable MaxNumOfItems(), but rendering
     does not need to handle all allocated memory blocks making rendering run significantly faster. Difference is like 330 -> 18 style
     improvement of number of instances rendered during lod operations.
 4) web pages have fake AI web template -- the actual AI part still not implemented
 5) matrix multiplication was optimized
 6) acesfilm colour changes implemented to the shaders.
