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
I suggest:
```
int buildin_recovery_ALL_pc(struct map_session_data* sd, va_list ap) {
    int revive = va_arg(ap, int);
    return buildin_recovery_sub(sd,revive);
}
```
Uses the return value passed by `buildin_recovery_sub` and passes it on to the caller.
