Forbid sending an equipped NFT

[mrshiposha]

I suggest forbidding sending of an equipped NFT. I believe sending an equipped NFT can lead to exploits like #185...
Also, I think that it is logically more accurate to unequip an equipped NFT first and then send it to some user/token.

@mrshiposha thanks for the reporting. In Kusama rmrk-tools version we unequip during sending. Ideally to have feature parity, so will look into that.

I think forbidding SEND would be difficult as send is part of rmrk-core, but equip (and the Equippings storage) is part of rmrk-equip...and unequipping during SEND would be difficult for the same reason...

But there is an equipped flag inside the NftInfo (which is a part of RMRK core). Maybe it could be used to prevent sending of an equipped NFT?
