Modified BufferObject.java to support partial binding and specific port
binding, so it can be used as uniform buffer. Modified matrix class by
adding separate size functions to get column an row count individually.
Also added a matrix container, that manages modelview and projection
matrices. It can not push and pop matrices though. This function and an
updated Javadoc will be part of the next commit.
