Implement extra spell gems!

New limits:
    Tit: 9
    SoF: 9
    SoD: 10
    UF: 12
    RoF: 12
    RoF2: 12

The SoF client doesn't actually support 10 like SoF should
RoF/RoF2 actually have 4 extra broken spell gems in the UI. They don't work and
will likely crash your client

Quest stuff assumes you are passing in valid slots.
(note the old default of 10 should be 22)

There are still somethings to do like clean up the memmed spells if one switches
to an older client that doesn't support as many as their previous client.
