*  This script will accept touches.  When tocuhed it will tell the mod_touchable-1.0.lsl script to send a touch event to the server
*  That touch action will check to see if the user has X water in their inventory, and if so, subtract water 
* Once watered 5 times, this script will rezz a flower object, and shout out the person the flower object should float towards
* Once the flower object reaches its target it will tell this plant object to give the user a flower in their inventory
