Add vim macro recording and playback

q{register} records keys into a register, and @{register} plays them
back, with a count, @@ for the last macro, @: for the last ex command,
and @+ for the clipboard. Playback stops at the first failing command,
so 100@a and recursive macros work as in vim.

Insert mode keys from macros and '.' are now typed into the text area
as key events, so that auto-indentation etc. behave as when recorded.
