Added verb frames

In addition:
- Added prepositions.
- Rewrote a lot of the query interface. It now, for a lot of relationships, supports nested AND, OR, and NOT logic.
- Rewrote the token class. It is now a union-like class instead of being polymorphic, which means smart pointers are no longer necessary.
- Querying with regards to word derivation has been temporarily removed.
- Sentinel values are now supported for all word types.
- The VerbNet data retrieved from http://verbs.colorado.edu/~mpalmer/projects/verbnet/downloads.html was found to not be perfectly satisfactory in some regards, especially regarding adjective phrases. A patch file is now included in the repository describing the changes made to the VerbNet v3.2 download for the canonical verbly datafile.
