* Code cleanup.
When copying files, if the target file already exists, append (1), (2), etc onto the file (this is enhancing existing implementation to allow multiple numbers)
* Added a ton of null checks to UpdateSeriesMetadata and made the code work on the rare case (not really possible) that SeriesMetadata doesn't exist.
* Updated Genre code to use strings to ensure a better, more fault tolerant update experience.
* More cleanup on the codebase
* Fixed a bug where Series SortName was getting emptied on file scan
* Fixed a bad copy
* Fixed unit tests
* Fixed a bug where the bottom of the page could be cut off
* Adjusted all the headings to h2, which looks better
* Refactored GetSeriesDetail to actually map the names inside the code so the UI just displays.
* Put in some basic improvements to OPDS by using Series Detail type layout, but this only reduces one click.
* Fixed a bug where offset from scrollbar fix causes readers to be cutoff.
* Fixed a bug where adding multiple series to reading list would throw an error on UI, but it was successful.
* When a series has a reading list, we now show the connection on Series detail.
* Removed all baseurl code from UI and not-connected component since we no longer use it.
* Fixed tag badges not showing a border. Added last read time to the series detail page
* Fixed up error interceptor to remove no-connection code
* Changed implementation for series detail. Book libraries will never send chapters back. Volume 0 volumes will not be sent in volumes ever. Fixed up more renaming logic on books to send more accurate representations to the UI.
* Cleaned up the selected tab and tab display logic
* Fixed a bad where statement in reading lists for series
* Fixed up tab logic again
* Fixed a small margin on search backdrop
* Made badge expander button smaller to align with badges
* Fixed a few UIs due to .form-group and .form-row being removed
* Updated Theme component page to help with style testing
* Added more components to theme tester
* Cleaned up some styling
* Fixed opacity on search item hover
* Fixed a bug where reading list and collection's summary wouldn't render newlines
* Moved all the logic in the UI for Series Detail into the backend (messy code). We are averaging 400ms max with much optimizations available. Next step is to refactor out of controller and provide unit tests.
* Unit tests for CleanSpecialTitle
* Laid out foundation for testing major code in SeriesController.
* Refactored code so that read doesn't need to be disabled on page load. SeriesId doesn't need the series to actually load.
* Removed old property from Volume
* Changed tagbadge font size to rem.
* Refactored some methods from SeriesController.cs into SeriesService.cs
* UpdateRating unit tested
* Wrote unit tests for SeriesDetail
* Worked up some code where books are rendered only as volumes. However, looks like I will need to use Chapters to better support series_index as floats.
* Refactored Series Detail to change Volume Name on Book libraries to have book name and series_index.
* Some cleanup on the code
* DeleteMultipleSeries test is hard. Going to skip.
* Removed some debug code and make all tabs Books for Book library Type
