Fixes for cover and renamed and browser functionality

Fixed crash when renaming zips - Not totally fixed
Added browsing functional to browser, including filtering and paginating

Project is not dead, it was just hibernating
Added opening functionality to browser

+ Can now open doujins from browser
+ Displays doujin info in right column again
- Can’t filter by tag yet
Fixed pagination

+ Fixed problem with crashing when going to next page
Fixed pagination

+ Fixed it better (because I didn’t actually fix it and made it worse)
Fixed filtering by contents

+ Can now filter by contents
- Had to use raw SQL since weird bug that seems to stem from contents
being LongUnicode with Pony ORM
Added search bar

+ Search through doujins with search bar
+ Search specific column using this format “@[column]:[query]”
+ Normal searches try to match via doujin title
- Needs tweaking and fine tuning still
Fixed unicode error

Fucking Python 2 and its shitty unicode system. I’m pretty sick of it.
Added filtering by label clicks

+ Clicking side labels on the right then searches for the label’s
contents
+ Can now use a pipe character in the specific search to search for
multiple things
Altered search box and menu behaviour

- Trying to change the drop down menus when there is something in the
search box now does nothing until the search box is empty again
- After search box is cleared, nothing is shown instead of doing random
again
Fixed yet another unicode error
Tried fixing the renamer

Tried fixing it, but it’s fucked beyond repair, I’m going just rewrite
it.
I don’t know what the hell is going on with it
Started trying to fix exceptions/error system

Trying to improve the errors system, because it’s pretty bad at the
moment
Moving to Windows for a while to test and stuff
Updated README.md
Added new error system

Implemented new error/exception system into config.py to start with
Clean up
Fixed major oversight

Files were being added to the database with the full path, relative to
current system. However, that'd be a problem if you had the database on
a remote server like I do.
Paths are now added without the 'in' path from config, and the config
'in'path will be added when opening from browser
Updated README.md
Updated README.md

The installer gave me the "_imaging module" error, and I couldn't be
bothered fixing it. The .egg works fine
Renamed README.md
Fixed opening archives under Windows
