Updated Irrigation Controller Device Type To V2

Version 2 of Smart Irrigation Controller Device Type For the SmartThings Ecosystem
This Device Type pairs with my Arduino Irrigation Controller V2 code base

Features of Version 2:
*Greatly improved communication reliability with Arduino by including a tokenizer to break apart communication messages that update multiple states.
*Station/zone times will now be automagically sent over when a station is turned on.  Therefore I eliminated the send stationTimes tile as well as the send stationTimes command
*Abbreviated some of the states to keep string lengths shorter
*Removed code for a message tile (it was not used)
