A quick maintenance release.
First a big thank you to user Ehsan Kia as he provided the code used in this release.
Ehsan had the problem where SimpleUndoClose stopped working after months and he had a large value set for saved tabs. He found out that theres a lot of orphaned closed tab entries clogging up the localstorage tripping the quota and triggering a limit.
The fix is to clean out any orphaned closed tab entries every time Chrome starts.
This could be the fix for all users who set large values set for saved tabs.
