Added throwing nets. These still need work, and thus

are not for 0.3. Obviously.

Summary: 
New item type MI_THROWING_NET. 
The enchantment of a net describes its state, i.e. 
whether it's brand-new or almost falling apart 
(happens at -8).

New attribute ATTR_CAUGHT (for monsters ENCH_CAUGHT)
that means the victim cannot move and instead 
struggles against the net until it manages to wriggle 
out of it (takes a while depending on size) or it 
is destroyed.
Monsters can still use items and spells when trapped.

New trap type TRAP_NET that currently is the only
source of throwing nets, though Gladiators (and some
types of hunters maybe?) should start with a few, and
David suggested also allowing the creation of nets 
for shops.
