This is necessary because the stupid client constantly spams right-click actions if you carry on trying to eat/throw/whatever the item when cooldown is in effect. Therefore ender pearls would be fired like machine guns without these checks server side.
This supports vanilla placement of paintings, with overlap and collision checking.
Paintings are removed when a block is placed inside them or if any of their supporting blocks are removed.
As per vanilla, a random painting is chosen from the largest subset that will fit into the given space.
Currently an ItemBlock is created for every Block requested, but this will need to change in the future (for Anvils because they have stupid bitshifts on the meta instead of a nice bitmask). This allows registering items in the ItemFactory with IDs lower than 256 and having them recognized.
This allows retrieving the name of an item without the custom name being plastered over the top. This will also allow weird things to have special functions for their names.
These are never called accidentally, or at least it's highly unlikely to do so. It might be reasonable to throw exceptions for this, but for the meantime they are redundant - extra indentation for no good reason.
This also removes the $force parameter from BlockFactory::init().
Wanting initialized item factory does not require initializing the creative inventory. This is often useless and unwanted extra baggage (when this is used on threads for example).
It's only now used in the Durable class, so it does not make sense to keep it in Item anymore. This is a leftover from the days where Durable did not exist.
First working enchantment on master. Hooray for 3 years late.
This works out of the box (the code checking for this enchantment already exists in Human->doAirSupplyTick()).
The remaining methods, constants and fields in the NBT class now pertain to generic NBT functionality (except for the matchList()/matchTree() methods, but that's a job for another time). All NBT I/O specific logic has now been moved to NBTStream and its descendents.
