An Alias for "//set air"

Desired feature:

Implement “//delete” as an alias for “//set air”

Why this is a good idea:

Too often, I find that I have to use //set air to delete a World Edit selection. While this is logical, I find that //delete is also an intuitive command. Moreover, “//delete” is one character shorter than “//set air”, and it only uses five unique characters, whereas “//set air” uses eight unique characters. Thus, “//delete” can be more easily typed than “//set air”. Furthermore, “//delete” does not already exist as a command, so it does not conflict with another command.
