Enhancements:
- The feed handling interface has been resurrected.
- An option to set Wizz RSS as the default feed handler has been added.
- Thanks to reptail, the fi-FI locale has been updated.
- Thanks to Wac?aw Jacek, the pl-PL locale was added.
- Font size options have been extended to include font sizes of 18, 20 and 22 pixels. Requested by benphane.
- Fixed bug importing OPML where the feed home URL was not read. Reported by crehberg.
- Fixed bug importing OPML where the feed status was not read. Reported by crehberg.
- Implemented code changes so that feed status and feed home URL will be persisted and restored when using the Save Feeds to Server and the Restore Feeds from Server functionality.
- Implemented the use of a pref to override the history checking. To override the history checking, create a boolean pref called WizzRSSSkipHistCheck and set its value to true.
- Fixed the chrome.manifest file so that the fi-FI locale will actually be used.
- Implemented a change that will detect (I hope) when Wizz RSS is un-installed. On detecting un-installation, the code will offer to remove the Wizz RSS folder. This one is especially for the anal retentive whiners.
