* Added BuildRequires: desktop-file-utils for desktop-file-install and desktop-file-validate.
* Added definition for _pkgdocdir at top for targets that don't specify it.
* Moved dev subpackage and contrib subpackage before doc subpackage, since it now uses a %pre.
* Added %doc entries for various bits of documentation.
* Modified %files devel to grab everything under _includedir/name.
