Started adding files for schema 1.5.0
Added to the interface for schema 1.5 files (work in progress).
Added dependencies for HK2.
Added a set of HK2 contracts for the SPI.
Started the HK2 version of Schema1.5 loading.
Refactored some of the data apis for schema 1.5, etc.
Wrote a simple test for the Collada 1.5 loader.
Renamed project back to JCollada because it's easier to use.
Removed the 1.4 schema from the main build until the api stabalizes a bit more.
Added types to interact with new general schema types.
Updated the hk2 version, and added a perthread context handler.
Added some more processing for the shader elements.
Updated the README - sometimes I make bad naming choices.
Added gradle wrapper & scripts.
Added IntelliJ ignores.
Removed old maven files and started using new gradle files.
Removed some unneeded files and started looking at the 1.4 project again.
Added copyright headers to the files - IntelliJ is pretty neat with it's macros.
