Add vimdoc documentation

For now, this is just the README.rst file with appropriate sections. The
content of the file itself is completely unchanged.

Section name suggestions are taken from Steve Losh's Learn Vimscript the
Hard Way [1]. Formatting suggestions are taken from Vim's own
documentation on writing help files (:help help-writing).

The spiffy header was created using the figlet program [2] and the
starwars.flf font found in the figlet fonts database [3].
