- Added support for 'unassigned' pile (buyNow items go here!)
- Amended sendToTradepile to support moving items from unassigned pile
- auctionParse small function added to parser 'unassigned' items
  -> added a few intersted attributes: injuryGames, lastSalePrice, etc.

- getCredits function added just in case you need it separated.

- keepalive function to keep connection with servers open
- removed some comments from piles functions
cleanup
core: make itemParse compatible with unassigned method
core: remote auctionParse
core: remote getCredits (use fut.credits instead) & fix keepalive

Looks like keepalive needs completly different headers (cookies etc.) so we're refreshing credits instead - much less code needed.
core: add injuryGames, lastSalePrice, fitness to item dictionary
core: update credits at the end of login method
urls: remove unused keepalive
core: fix credits
