Better desktop integration for GNOME

I really don't like the way the desktop file forces weird behavior
between IntelliJ IDEA, Oracle SQL Developer and other Java thick clients
that don't set their main window classname.
Include kvm utilities for troubleshooting

Include the following utilities:
  * kvm_stat
  * kvm_flightrecorder
  * tracetool.py
  * simpletrace.py
  * cleanup-trace-events.pl

These tools are left out of both the core qemu package and the qemu-git
package in the AUR. As such, it's a bit more difficult to do
troubleshooting out-of-the-box.
Remove delay when opening read-only files
Bump the gvim-hg PKGBUILD.
FlexGet runtime deps update. Bump to 1.2.189.

FlexGet needs python2-path and python2-guessit for runtime.

Bump to FlexGet 1.2.189.
Flexget version bump and dep change

 * Flexget is now 1.2.199
 * Turns out that python2-setuptools is a build dep - go figure
 * Can remove python2-argparse, since that's supposed to be a part of
   the python2 core package, and python2-stevedore has been fixed to not
   call that dependency out explicitly.
