Allow all weapons to use with any skills without switching weapons

[Neleth-KT]

Giving penalty damage when using a weapon that's not originally support by skills -25%

For example ability to use great sword with shield skills with -25% damage in case of templar.
This feature would be really helpful for a gunner where intensive switching weapon is must between pistols and a cannon.It will help these who can't switch weapons well but there's still a purpose for those who still want to switch weapons for extra damage.

Temp : Shield with punishment.
Ranger : Counterattack with bow.
