Players can not pick up stained glass. (old locked chest id)

[Anna Bakker]

Players are spammed with "You can not pick up this item" when trying to pick up stained glass which uses the same id as lockedchest/steveochest which was a block only obtainable from admin commands before 1.7.

Allow players to pick up stained glass, resolves #105
