Major Library Changes

Major Library Changes
-I've in the process of restructuring a lot of how BagSync is setup.  To that end I'm moving lots of the libraries as submodules so they are always updated.
-It's been a long time coming, but I've gone ahead and updated the LibItemSearch library to version 1.2 since BagSync has been using the old 1.0 for quite some time.
-Added the extra libraries that are needed for LibItemSearch-1.2 to work.  Special thanks to jailborc for all his work on the fork of Tuller's original code.
-Updated the class filter for the Search window to support the new LibItemSearch-1.2.  It still doesn't come with the library so I have to force the implementation of the filter.
-Some more cleaning here and there.
