Allow for getting help on key bindings

Browse Source 
In addition to getting help on specific topics, users can type things
like ":help s" or ":help ^A" to get help on specific key bindings now.
Note that we do not add help texts for these keys here -- we will alias
key bindings to already existing topics in a follow-up patch.
