Patch #20037: Use named components for Drivers instead of array_index

This patch, by Elia Sarti (vekoon), simply adds the possibility to specify the final array component of the RNA path in the path itself, 
e.g. using location[0] or location["x"] or even location.x,  
instead of specifying this using an "array_index"

This should be easier for users to understand the driver system. The array-indices have been kept (but hidden from the UI under standard situations) since they are theoretically a tad faster than the in-path lookups still, and are easier for internal-tools to set for now...
