- removed the EnvExpand recusion limits as this didn't work in the production env which
has more than 30 env vars. might want to add limits in later if this becomes a problem.

Inital pass at searchpath impl
- added environment variable string expansion code in PathUtils.h (GetEnvMap() & EnvExpand())
- added FileExists() function to PathUtils.h
- added searchpath functionality into Config:: class (setSearchPath(path), getSearchPath(expand), findFile(filename)) this hasn't be plugged into anything yet.
- added ocio_core_tests.sh.in so we can pass in some env vars for the unit tests
