Update *recovery script command

another script command that rathena already having for months
http://trac.rathena.org/changeset/17321/rathena

no more atcommand @raise, @raisemap or @alive

feel free to improve the code
It's overkill to add such a script just to explain a command because documentation fails at it. I'd remove the example script and update the documentation, so that scripters will only have to look at one place.
