als / addlabelstyle           Adds a map label style

   Format:
      ;als <name>
      ;als <name> <text>
      ;als <name> <text> <underlay>
               Adds a style called <name>

   Notes:
      Map labels are drawn in the automapper window. It's possible to customise
         labels individually, but most labels are drawn using a map label style
         (so that when the style is changed, all labels using that style are
         redrawn automatically).
      <name> can contain any text (maximum 16 characters). If it contains
         spaces, you should enclose the name in diamond brackets <...>.
      <text>, if specified, is the text colour. You can specify any Axmud colour
         tag (including xterm and RGB colour tags). If <text> is not specified,
         a default colour is used.
      <underlay>, if specified, is the underlay (background) colour for the
         label. You can specify any Axmud colour tag (including xterm and RGB
         colour tags). It's not necessary to specify an underlay tag; both
         'RED' and 'UL_RED' are acceptable. If <underlay> is not specified, the
         label is drawn without an underlay.
