Initial Commit
Mostly-working implementation that just needs cleanup now.
No build issues aside from the expected "May not respond to"/"Method not found" warnings for added selectors.
Added WoolObjCEncoding, which contains functions duplicating objc/objc-typeencoding.m for handling type encoding strings, as well as a custom function to insert the encoding for a selector into the correct place in an arbitrary method signature string. This allowed the finalization of -[WoolDelegate methodSignatureForSelector:]. That method now checks first for a signature having already been set, then for a signature in adopted protocols, then modifies the appropriate Block's.

General comment and formatting cleanup.
Ready for publication.
