Removed adam's Library Search Paths

• Removed a number of Library Search Paths from the xcodeproj that were pointing to hard-coded `/Users/adam/workspace/openFrameworks/addons/ofxTimeline/libs/…` dirs.
	» They were producing linker warnings like: `Directory not found for option '-L/Users/adam/workspace/openFrameworks/addons/ofxTimeline/libs/openal/libs/vs2010/EFX-Util_MT'`.
	» The fact that these are hard-coded paths, and that they include a library that OFPlugin doesn't use (ofxTimeline) seems evidence enough that this is just an unintended mistake.
