taste-tester and between-meals, first public release

Two gems we've been developeing and using internally:
* taste-tester - chef-zero based cookbook testing utility
* between-meals - common libs and utils for vcs-change calculation and processing, to be shared between the projects

Props to @jaymzh for his contributions to this,
* multi-VCS abstraction and SVN support
* awesome config-file and command-line support
* miscellaneous bugfixes and tweaks all over the code
