Metadata Fixes

[majora2007]

A quick set of fixes based on the feedback from yesterday. This is just a bit to give me more time to tackle more of the bugs and some of the great suggestions that came out of the first day of testing. Looking forward to more suggestions.

Changed

• Changed: Allow existing genres/tags to contribute to the Age Rating mapping
• Changed: If anilist id is set, will add an AL weblink on person page
• Changed: Default to First Last naming convention as that is what Manga Manager and AniList use by default. (develop).

Fixed

• Fixed: Fixed an issue that caused breakage when Field Mappings was not set (develop)
• Fixed: Fixed the images in the changelog modal to be styled correctly
• Fixed: Fixed a lot of cases where locked fields weren't being respected (develop). I plan to add a new field to allow overwriting locked fields.
• Fixed: Fixed match button in Edit Series modal (develop)
• Fixed: Fixed Dont Match on manage matched throwing an nullable exception during mapping. (develop)
• Fixed: Fixed a typo in the event widget error message that shows up when the scan returns an empty root folder for the particular library. (Thanks @midhun3301)
• Fixed: When processing people from upstream, ensure we keep the existing metadata on hand for processing. (develop)
• Fixed: Fixed match series item not showing chapter/volume count when series was ended.
