Improvements to Character API

This commit adds default character and characters retrieved from API to
the DB, opening the door for "quick update" of API data (we now have api
details and character to update).
Added API update button near character selection

This make it easy to fix those "I can't fly this ship!?!? Oh wait, I
need to update the skills". A simple click and it fetches the data.
todo: disable button for characters without default char in database
