Subject: [PATCH] added selection preferences

- Added a drop-down that allows choosing between preferring scanlation groups based on who translated *most chapters in the entire manga* and *most up to each chapter*, defaulting to most in manga; the user can freely switch between modes to see which one they prefer
- Fixed a minor bug that prevented the download button from correctly updating to indicate download progress

+		- There is an option to instead prefer the group who covered most chapters *up to each chapter*, to allow consistency in chunks for mangas with spotty coverage  
 		- The program also offers a button to quickly unselect / reselect interlude chapters / extras, but be warned this is a "dumb" feature, it (un)selects the chapters with decimals, it has no way of knowing the actual content of the chapter  
 	- Choose which title to use - the program lets you choose between the main title and any alt-titles listed on MangaDex; the program tries to get the alt-titles in your preferred language  
 	- Downloaded mangas are ready to be read - after downloading, the program creates a single `.epub` file with all the chapters, the cover image, author and artist; alternatively, it can create a single `.cbz`, however this will have no metadata (the cover image is still included, as the first entry)
