Added isHarmlessAbility() to AbilityModule

Will be used with Region Protection, currently not a runnable build.
isIgniteAbility() and isExplodeAbility() added

For Region Protection. ProjectKorra respects explosion and fire flags in
various plugins, so this will allow an ability to register as such.
isIgnite() means the ability produces fire (Like Blaze) and
isExplodeAbility() means the ability produces an explode (Like FireBlast
and Lightning)
Region Protection

Should work *flawlessly* on all abilities.
