Large update to pc-mounttray:

1) Convert over to running with user permissions
2) All devices will now be mounted in the ~/Media directory (it gets created as necessary when the application starts up)
3) If a device gets a permissions error when mounting, it will immediately fall back to asking the user to mount the device as root with pc-su.
4) Once a device is flagged as requiring root permissions, it will update the icon with a little yellow shield in the corner for easy identification.

Currently tested with FAT, NTFS, UFS, and ISO/CD9660 filesystems.
Some new quirks:
1) The first FAT device to get mounted after system bootup will require root permissions, while subsequent FAT devices/mounts will only need user perms. This is because of a FreeBSD bug in mount_ntfs when the localization flag is used (-L=<mylocale>)
2) NTFS filesystems appear to always need root permissions to mount (have not explicitly flagged that filesystem for root yet until after additional testing)
