added 3rd party dependencies ( except Jedi-SDL )
modified DPR to statically include all files needed (using relative paths) this means 3rd party components should not need installation in the IDE, or adding to search paths. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@368 b956fd51-792f-4845-bead-9b4dfca2ff2c
