begin 0.2.0 dev work

0.1.0 might be sitting in the web store "Pending Review" queue, but that's no reason not to work on the next update.

~ Updates manifest.json to reflect a move to 0.2.0
+ Implements functionality for "Reset" button on options page (which was forgotten about with v0.1.0)
most of edit JS implemented

still need to write function to store the edits. This will probably be in next commit.
primarily manifest changes

+ Adding a rule now clears the inputs upon success
+ Added update URL for extension
~ Extension permissions adjusted (no longer requires tabs)
close #2 + rename to "Injector"
fix #3
