Small changes

Changed code formating to my liking. Tried to add number index to menu.
Needs testing.
Merge branch 'master' into development
Added Adafruit Libraries, since global python packages are not working at the moment.

Inserted try:, except: and finally: statements for the menu code to handle LCD shutoff.

Tried to get lenth of dict and add it to a copy of itself, did not work. Lets try to get list length next.
Edited the install script

Removed git-core package, added pip install for adafruit libraries,
commented out the general part of rc.local (prevents overwriting an
existing start script), commented on the use of modprobe
Minor variable name and function call adjustments

On LCD initialization let Adafruit's code determine the RPi model,
changed reverse ssh host ip variable name from 'connectingClientIP' to
'ssh_reverseIP'
Changed structure of menu

Using tuples and ordered dict instead. Need to check line 289. Does that
globals() call work?
Fixed indentitaion errors. All the new code works - merging to master.
