Fixed regexes, formatting

- fixed kismet regex so it will not ever overide other dice (aggressive
  negative lookahead assertions)
- made main formatting attributes properties in some rollers to make
  other properties format-able.
- added some constraints to kismet and white wolf dice for targets.
Messed with vendored directory
Updated vendor script to pip

The vendor script was renamed to `vendor.sh`, and updated to use pip,
and pypi instead of git or svn.  Can now install anything from pypi
