Man page improvements

* Removed the AUTHORS section as recommended by man-pages(7),
  the conventions for writing Linux man pages.
* Change the secion name to the more commonly used "User Commands".
* Don't say "this man page might be out dated".
* Always use the current version number of compton as "man version" in
  the man pages.

Also bumped the project version in meson.build
