title: Errors when including hyphens in table variables
body: <p>I recently bought MaterialBoard from ScriptFodder. I am editing the groups list so it will show the capitalized &amp; un-hyphened group names so instead of head-admin it would look like "Head Admin". Everything has worked so far but once it started using hyphens in the variable name, it concluded errors:</p>
  
  <pre><code>[ERROR] addons/materialboard/lua/matboard_config.lua:76: '}' expected (to close '{' at line 73) near '='
      1. unknown - addons/materialboard/lua/matboard_config.lua:0
  </code></pre>
  
  <p>how do I make it so I can include hyphens in a table variable name like this?</p>
  
  <pre><code>co-owner   = "Co-Owner",
  </code></pre>
