Update Notifier Crash Patch

- This patch adds a stupidly missed return statement in the catching of
trying to get the resources from the internet. This may need to be
updated in future to a user defined option.
- Updated build.gradle,, update.txt, and the Strings library class.
- MOST IMPORTANT: added a 1.7.2 build of version 2.2.2 to the update
folder. This will NEED to be removed once you get the commit.
