Free up 'docs' directory for actual documentation

* Moved man pages to 'man' directory
* Moved mime info to 'mime' directory
* Moved tiled.desktop, tiled.appdata.xml and Doxyfile to root

The 'docs' directory is now planned to contain the Tiled Manual.

The outdated map.dtd and map.xsd files are still there. I think they may
be useful to have in the manual, if they are updated of course.
