Changes Proposed

Liete mentioned that skills don't check if the equipped ammunition type is appropriate for equipped weapon and thus can be cast with wrong ammunition type equipped.

Hello.
Can anyone help me out with this issue:
I have set certain skill - Spread Shot to be working with grenade launchers, but there is a problem it uses both bullets and grenades be it shotgun or launcher equipped.

The actual problem is that you can equip bullets or grenades regardless of the equipped weapon type. This issue has already been reported: #2579
Since this needs some more information before completely get fixed this PR is a quick workaround for the time being.

Issues addressed: #2661, Partially #2579
Closes #2661

Wasn't this intended for example, an assassin is able to wear arrows and gain effects on Grimtooth, is that an athena thing or maybe pre-re thing? regardless I would like to have a battle conf for this one.

This change doesn't affect Grimtooth+Arrows. Grimtooth doesn't have Requirements->AmmoTypes defined, so the changed code block is never reached. Thus there is no need for a battle flag.

Alright, thank you for clarifying that.
