Phoebe related charsheet changes

This is my first round of Phoebe related charsheet changes.

This patch only addresses thing that I have noticed broke with various changes API/SDE changes.

SDE: Some skill description contained quotes (coloring for "Skill can not be trained on trial account")
API: Skills were assumed to be the first "rowset" in the character sheet
API: All implants are exposed, with the old "attribute modifier" method being removed
Maybe replacing &quot; would seem cleaner, actually django.utils.html.escape would be cleanest as it's a bit more future proof against :ccp: adding more stupid crap
