This is just the packet framework for the Scribe button on recipe books
and the Cast Spell button on books that allow casting spells on
targets. It will need to be hooked up to a content implementation
This adds the `dz_switch_id` field to doors and dynamic_zones. It will
allow for compasses to be automatically added to dz entrances and will
support moving clients to the dz on use without needing to script it.
These can be imported for switches/doors from live packet dumps.
Also removes compass packet encoders (same struct in all clients)
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.
