/*
        I stole this from Helpbot, and modified it to take a targetlevel
        and a requestor level instead of a percentage.
        I also modified the return value to be just a HTML color code (#XXXXXX)
        Thanks Beaker for this handy function! http://www.kuren.org/ao/helpbot/

        This function returns the color code of the color the hp bar that a
        player of requestorlevel would see for a player of targetlevel.
        ie:
        if requestorlevel is 220 and targetlevel is 5, a grey color code would be returned.
        if requestorlevel is 220 and targetlevel is 200, a greenish color code would be returned.
        if requesterlevel is 200 and targetlevel is 220, a orangish/redish color code would be returned.
        if requestorlevel and targetlevel are equal, a yello color code is returned.
