1. delete EXPRESSION from usage in BANNER, because user can use EXPRESSION only when -e option is given.
2. add `show-source Pry.foo -e` example to BANNER.
3. rename parameter of options method from `opts` to `opt`, because in other commands `opt` is used.
evaluates the argument to the pry command as an expression and returns
the source for the return value of the expression. i need to add tests
as well as update changelog.

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.

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!).

Pry::CodeObject::Helpers mixin provides the following methods:
command?
module_with_yard_docs?
real_method_object?
c_method?
which are then mixed into the code objects: Pry::Command, Pry::Method, Pry::WrappedModule, Pry::WrappedModule::Candidate
Until we find a better home for it, the code for the complete() method is exactly
the same in each case so we should come up with a way for show-source/show-doc to share it.
