Current Momentum

v2.8

for 2.2 I've added a dedicated tablet view that better uses the tablet screen. I've also added support for the reader comic book formats. CBZ/CBR . I've also updated the password scheme to work better with calibre password protected libraries. I added multi library support as requested and fixed the pdf issues we were having. I'v modified pdf view to better handle scanned books more like the comic book reader. Newly added the ability to add libraries from calibre web among other sources.
