Merge notification and fuzzy match branches

this pull request combines ianHanniballake/ComicUpdater#3 and ianHanniballake/ComicUpdater#4

so if you pull this then there is no need to pull the other two.
Not sure if this is the correct way to do this though but pulling one and then the other will not work due to a conflict which is resolved in this pull request.

with kind regards
