Kyrylo Silin ebccd57013 Convert all commands to classes
John "banister" Mair describes the following key features of commands
as classes:

  1. It enables people to extend them by either subclassing or
     monkeypatching.
  2. It enables them to provide their own API, so that for example, the
     Pry::Command::Edit class could have class methods for people to
     configure it.

Please, note that I didn't touch easter eggs commands. I also prettified
some strings (your source code reading experience should vastly improve!).
