- Added setting clear_skills_on_warp to specify when a character's land-based skills are deleted when the caster changes maps. Defaults to all types.

- Should have fixed Brandish Spear not passing the flag to skill_attack, causing it to do miserable damage.
- Warp Portal will no longer be removed when caster steps through it (this is left to the new clear_skills_on_warp setting)
- Cleaned up status_percent_change to switch equations when the target has high hp to prevent overflows, also it will directly take hp/maxhp when a rate of 100 or higher is passed to prevent calculations.
- Traps and Land Elemental fields are no longer automatically removed on map change (handled now by clear_skills_on_warp)
- traps_setting &2 no longer does anything (handled now by blah blah)
