change to support fifo
remove double quotes with extreme prejudice
remove a useless comment[
I removed some comments in the last commit too, but I was too dumb to
say that I removed them in that commit message, so the notification is
going in this one instead. Oops.
REFACTOR EVERYTHING
wow, this is a lot of changes in a single commit, and I know that's
awful, but here they are
 - we now only use one command, /prefix
 - we now support both FIFO and in-weechat servers in one script!
 - general refactoring
add readme, again
