Replace the old default AI code with the ai_generic arch. Server startup will fail if it's missing or not a valid AI object.

Fix 2 copy-paste errors which double-generated mob abilities rather than generating randomitems and abilities

Add missing const to plugin declarations

Copy commands which were inadvertently deleted in the previous commit.

Reorder loader command array to group similar commands, and add an extra argument to some of the macros since the GCC preprocessor cannot paste variables to operators.

Fix warnings that VS treats as errors by default. Mainly unused variables and implicit casts.

Replace labels used as variables in the loader code with functions because Visual Studio doesn't allow labels as variables. This also allows deduplicating code which is common between various object fields, like str/dex/name/resists.

Replace legacy wc_add/ac_add/dam_add with the new +wc/+ac/+dam
