Subject: Refactor command-option parsing.

When we introduced command options (for mapping keys to custom-search
engines), the parsing was done in the Vomnibar code.

This moves the parsing to `commands.coffee`, which is where it should
always have been.

This is a preliminary step with a view to adding a new `count` command
option.
