Bulk and fixes

Base bulk system is implemented and it required some changes in backend database structure so you may need to hand update weapons/attacks. In case you are not able to open item or character sheet just export it and recreate new ones by copy pasting data from exported file into new one. It should not be needed but one can never be sure.

I don't recommend updating in the middle of campaign as it may be pain to fixup everything unless you are willing to fix it by hand!
