+WORK THAT NEEDS TO BE DONE HERE:
+================================
+- the current version is taken from prefs and stored in cUV (ln 28)
+- a way needs to be found to access cUV from a function
+- source code from test needs to be incorporated into here and the .html
+- a more elaborate update notification needs to be designed and properly placed in the rzHome page
+- then it needs to be hidden
+- build and test this source code
+- bitch at XUL when it tells you that you can't access outside scripts from a chrome process (hopefully not, but it's likely)
+- once this all works clean up this clusterfuck of a script
