Add spec file for building in RPM-based systems.

Spec file creates the following packages:
* mu: The main email indexer, with mu4e included for emacs
* mu-gtk: with the mug executable
* mu-guile: with the bindings for guile

As per the Fedora Packaging Guidelines, there should not be a separate
emacs-mu package if the main package (mu) does not require emacs, but it
provides additional files for its use with emacs. I think that's the
point of mu4e.

+%description
+E-mail is the 'flow' in the work flow of many people. Consequently, one spends a lot of time searching for old e-mails, to dig up some important piece of information. With people having tens of thousands of e-mails (or more), this is becoming harder and harder. How to find that one e-mail in an ever-growing haystack?
+Enter mu.
+'mu' is a set of command-line tools for Linux/Unix that enable you to quickly find the e-mails you are looking for, assuming that you store your e-mails in Maildirs (if you don't know what 'Maildirs' are, you are probably not using them).
