Finish Phoebe updates (BREAKS COMPAT)

Note: the following changes break reverse compatibility with previous released versions of EVELink:

* The 'attributeEnhancers' portion of the char/CharacterSheet was removed.
  As such, the 'bonus' and 'total' fields have been removed from the attributes
  dictionary on the return from character_sheet(). You will need to calculate
  these bonuses yourself using the new 'implants' data provided.

Other updates in this patch include jump clone data (including implants), home station, respec info, and free sp info.
I don't want to leave it there permanently, but it's the easiest way to alleviate confusion if someone is relying on the `total` field and wondering where it went.
