Some nice changes

I have fixed up a couple of things that I wanted, you also may find them useful.

* Added https for trakt
* Fixed scraping of season and episode numbers from myepisodes
* Separate out my episodes user and password from code
* Added collection updating
* Tidied up README
* Replaced tabs with spaces (sorry).

The season and episode numbers are currently formatted as the following, so I removed the old regex: "\<td class="longnumber"\>01x01\</td\>"
