Fix several issues with pc-update manager:

 * Fix package cache location / usage
 * Fix detection of SYSBASE to be misc/pcbsd-base if flag is set
 * Fix an issue with conflicting FreeBSD pkg repo
Remove the bluetooth utilities from src-qt5: The bluetooth stack on FreeBSD is woefully out of date and inoperable. Once FreeBSD updates the bluetooth stack, we can look at creating new bluetooth utilites again.
Merge branch 'master' of github.com:pcbsd/pcbsd
Convert pc-zmanager to Qt5
Fix the virtualbox xorg.conf template to disable AIGLX
Convert qsudo to Qt5
Convert warden-gui to Qt5
Merge branch 'master' of github.com:pcbsd/pcbsd
Move syscache to running "pkg upgrade -n" directly to check for pkg updates instead of using pc-updatemanager pkgcheck. This prevents possible "loops" in update check pings.
Update the src-qt5 port files (could still be errors)
Add full logging to pc-updatemanager commands

Now a duplicate of all console output will be sent to:
/var/log/pc-updatemanager.log

Fix an issue with using CUSTOM repo URLs, now we can set
%VERSION% and %ARCH% in the repo string, which will be parsed
out during regeneration of the pcbsd.conf pkg repo files
Merge branch 'master' of github.com:pcbsd/pcbsd
Add conversion of %VERSION% & %ARCH% during major system updates also
Patch the pc-systemupdatertray (qt4/5) this prevents the constant 1 minute refresh timer.

Start fixing up the port files for Qt5
Update Syscache to Qt5 (and modify the port Makefile to account for it - needs testing)
Merge branch 'master' of github.com:pcbsd/pcbsd
Fix syscache/portfiles
Clean up the overall src-qt5 directory and extra files a bit
