Subject: //metasave and //metaload are now superceded by //save and //load's
new functionality. worldedit.deserialize now supports every version of the
WorldEdit format that has ever existed, and the new worldedit.valueversion
uses file characteristics to determine which type of file format a given file
uses. The new WorldEdit file format is the same as the one used by MineTest
for serializing data, and is capable of storing arbitrary data, as well as
leaving fields for future improvements. In other words, this is the last
forward-compatibility breaking change that will be made to the file format.
