Subject: [PATCH] Added some basic relocation mapping support for when loading
 hypergrid links from a xml file. Console Command: link-mapping <StartXloc>
 <StartYloc>. This results in only the last two digits of any of the locations
 defined in the xml file being used, and those 0-99 values being added to the
 StartXloc and StartYloc figures. For more infomation, see the email on the
 mailing list and the soon to be added instructions on the wiki's hypergrid
 page. Also made the Secion Names in xml file case insensitive.
