Tweaked description text a bit
Updated spec to use rest-client
Fixed a typo
Updated the path casting so it uses the Ruby PATH environment variable instead of the system's since the system call spawned a new process and didn't persist the path value. Also refactored the registry configuration to use the Ruby standard library for win32/registry. Fixes issue #5.
Bumped version
Merge branch 'release/0.2.2'
