Spell.cpp @ 108

Revision 108, 192.2 kB (checked in by yumileroy, 17 years ago)

[svn] Continue the work of rewriting spell target selection functions (warning: this may cause some spells broken).
Add some spell_script_target.
Delete some workaround in scripts (since core provides spell support now).
