Update plugin_pmount.py
Currently the pmount plugin uses static device letters and partition numbers. this change uses present devices and partitions.
- Changes the binds to remove the need for uppercase device letters, if a device has no partitions <alt><m or M><device letter> mounts/unmounts the device.
- With only one partition the same binds will handle it instead of the whole device.
- With greater than one partitions, map <alt><m or M><device letter><partition number> for each.

This is still not fully functional, devices not present when ranger is started *(usb drives)* won't have a map created unless ranger is restarted :| ... Is there a simple way to have ranger 'reload' this plugin, or use a different hook, etc.?
