add repeat command to make the same action again

The UI object now saves the last executed command (except for
RepeatCommands themselves and Promt- and FlushCommands, since they are
not user invoked, intended actions). The RepeatCommand then applies the
stored command again.
This is comparable to the . in vim, so I would recommend you add this
line to your config ;)

. = repeat
