A lot of changes, most of them under the hood--all in preparation for updates to come.

• Added a "Source" button to view mode, you can press this to open the source of the image in your browser.
• Custom Lua modules can now be loaded in from outside the program (this way updates won't delete them). They follow the same naming conventions seen in Zenith Grabber > resources. To add custom localizations: you need a "lang" folder in the directory. To add custom website handlers: you need a "website_handlers" folder in the directory.
• Added a setting option for the source key shortcut.
• Added a setting option for Lua custom modules directory.
• Added a page number indicator when viewing Doujinshi.
• Post data now supports tags, artists, and sources (all will be utilized in the future).
• Fixed a potential crash if a website handler module was written with errors.
• Added new classes to post.lua: PostImage, PostVideo, PostDoujin. Also updated existing website handlers to use these new classes instead of the base Post class.
• Updated the "zenith" Lua global to be written in purely Lua instead of being converted over (with the exception of json_to_table and xml_to_table).
• Videos are now recognized, but currently get skipped awaiting future implementation.
• Updated the localization files.
