Allow for specifying amount to increase itemstack in /more

Fixes #2342

Tried this out, but there seems like there is a bug checking stack sizes. If you do /more 1 with a stack of 63, you get an error, even though 64 is a valid default stack.

Honestly, I'd avoid adding these new errors, because they aren't very user friendly. In the case, for example, where I have a stack of 50, and use /more 20, I would personally prefer either 1) receiving a stack that is at it's maximum size (either default or over sized) or 2) receive that maximum stack (64), but then another stack in addition (6), given that inventory space permits.

PS: Do over sized stacks even work anymore? I thought they were patched out some time ago.

Do oversized stacks even work anymore? I thought they were patched out some time ago.

I know some clients can go over 64, but this is more intended for items like ender pearls or totems which are limited to stack sizes or 16 and 1 respectively which the client will happily handle bigger stack sizes for.
