Refactoring (#10) + Making `pod plugins` an abstract command (#11) with `search` as the default command (#12)
Small fixes in spec (removed argv function, removed commented-out line)
Merge branch 'CocoaPods/master' into 'AliSoftware/master'
Improved help message a bit
(see discussion in #11)
Added brackets around `QUERY` argument to let it show it's optional now.
* Adding the 'list' subcommand, making it the default
* Rollbacking to 'search' subcommand requiring a non-empty QUERY.
* Refactoring to mutualize code common to 'list' and 'search' in a PluginsHelper module

See discussion in #11 and #12
Removed useless `require` statement
small rdoc fixes
I'm a perfectionist.
Merge pull request #13 from AliSoftware/master
