Migrate to a class based traktAPI usage

- Move all traktJsonRequest calls to a traktAPI class.
- Startup notification and scrobler irregardless.
- Test account every call, save state after first successful call.
- Increase urllib2.urlopen timeout to 60 seconds, from 10 seconds.  Reason for this, when checking the plugin for MediaPortal, it uses C# Webclient which has a default timeout of 100 seconds.
- Rewrite getData, and verify all error scenarios (used own host to verify).
- Make traktAPI a bit more chatty for debugging.
- Switch back to JSON username/password for authentication (either way works).
- With debug logging, add ability to hide sensitive data from log.
- Setup ability to possibly implement a queue based system for non-important calls.
- Other changes/additions i probably forgot about.

This needs a bit of testing before being merged (if it gets merged), just to make sure I didn't miss any merges, since I merged this in from my debugging folder.

I've been testing this code for the past 9 days (on my live HTPC box), and have gathered some statistics (which are pasted below).

Also, since increasing the timeout to 60 seconds, imo it seems to be a bit more stable, I haven't seen it do any retries.  Also, haven't seen any 503 errors, so that part of it hasn't been thoroughly tested (would it be possible to have a test api to emulate a 503 error?)
