Cleanup some things

* Remove old login background [unused]
* Remove glock (graphical lock) [outdated]
* Have toolchain/activate set pkg-config variables
  XXX: You will have unset PKG_CONFIG_LIBDIR to configure native
  software if you have activated the toolchain! Otherwise, your
  pkgconfig information will be incorrect.
* Fixed a bug in the compositor where we would give window stack order 0
  to applications that didn't ask for it because depths were assigned by
  wid which starts at 0. Make it start at 1 instead, no chance of an app
  getting the wrong stack order (this shoudn't have any effect on how
  things work with a login app, since it grabs wid 0; but if you boot
  directly into a non-login environment, minor timing issues can do odd
  things.)
