* forgot to remove 'no_arg' from Pry::Command::CodeCollector, this method no longer exists
and so 'gist' (when not given any params) would break. Replaced no_arg with empty string ""
so that 'gist' gists current object/method by default.
Wrap command descriptions to 80 characters. Convert some string options
to symbols (where possible). Align options in code. Remove dots in the
end of switch descriptions.

And implement play and save-file using the new delegator. 'gist' still needs
to be re-implemented using CodeCollector.

TODO:
**************
Couldn't write a test for `play --lines 4..5` with implied target.eval("__FILE__") parameter,
need to come up with a decent test.
