Put GetName function in the interpreter

Each interpreter now have a GetName function, which will
return the name of the interpreter. We also put the interpreter
name into the logs by using this function so that it is much
easier to parse. Now, every interpreter name will be outputed with
the key "interpreterName" in log.

BUG=chromium-os:32513
TEST=Recompile the gesture library and generate the new log on the
chromebook. Then, you can see there is a label called "interpreterName".
