Revert to previous dictionary check behavior

The current version of FAVE-align does not automatically add new items to the local dictionary. As I understand it, the reasoning behind this was that we didn't want users of the website interface potentially adding all kinds of junk to the lab copy of CMU dict. This only makes sense for the website FAVE installation; users with their own FAVE installation shouldn't have to manually add items to their dictionary. 

These commits reverse that change in the code, so that dictionary items are once again automatically added. It also adds the dictionary file and FAVE-extract config file to the gitignore list so that changes to those files aren't tracked.
