"cbrestore" instead of "cbbackup" in cbbackup documentation example

There appears to be an error on the following page: http://docs.couchbase.com/admin/admin/CLI/cbbackup_tool.html

In the discussion of the cbbackup, the syntax provided is:

cbrestore [options] [backup-dir] [destination]

It is not as simple as changing 'cbrestore' to 'cbbackup' as 'cbbackup' actually has a different syntax:

cbbackup [options] source backup_dir

The above usage was copied directly from the `--help` of the 'cbbackup' command.

Note: This particular issue (wrong order of parameters) also affects the 4.x CLI docs for cbbackup too, although it is correctly labelled as 'cbbackup'.
