Houdoku V2.17.5

Full Changelog: V2.17.2...V2.17.5

I added a new tab in Settings called Theme.
In this new tab I moved the Theme settings (Light or Dark mode) that was in the General tab.
Also I added a generic Color Picker that currently allows the user to change the color for two settings.

1. The scrollbar slider/thumb located on the Main page.
2. The background color for the chapters count located on each Series card.

Added a new Sort button to the Main page. I moved all of the sort options to this new button. I also add a new sort option called Chapter Update. This allows you to sort series by the latest one to have a new chapter added.

Added a new option to the Layout button. It allows you to set how the All Series library page displays the Series cards. Currently all cards, despite their set category , are displayed.
Option 1: All, this option will show all Series cards despite what category they have set.
Option 2: Filter by Category, this option displays only those Series cards that do not have a category set.

Added to each Series card the date that series received a new chapter. Date is located below the series title.

The backup.json file is now readable, includes system settings, and much more organized.

I was able to get the version checker to work (portable version). After it determined there was an update available it asked if I wanted to update the program. I selected Yes. The program was updated and the version number shown in the program was correct. But the text of the exe was still stated it was the older version.
Still need to check the full install version to see what happens.
