Small change to Argon template

I added an option to the nice Argon dokuwiki template to get rid of the left sidebar. Here are the changes I made:

1. Changes to main.php (in lib/tpl/argon/)
   • Top of the file, below original line 10, add the line:

     $showLeftSidebar = !tpl_getConf('hideLeftSidebar');

   • Below line 133 (original line 132, after the left sidebar comment), add the line:

     <?php if ($showLeftSidebar) { ?>

   • Around line 198, after the code

     <!-- center content -->
     <main class="col-12 col-md-9 col-xl-8 py-md-3 pl-md-5 ct-content dokuwiki" role="main">

     add the following three lines:

     <?php } else { ?>
     <main class="col-12 col-md-115 col-xl-10 py-md-3 pl-md-5 ct-content dokuwiki" role="main">                  
     <?php }?>

2. Changes to default.php (in lib/tpl/argon/conf/)
   • Add:

     $conf['hideLeftSidebar']  = 0;

3. Changes to meta.php (in lib/tpl/argon/conf/)
   • Add:

     $meta['hideLeftSidebar']  = array('onoff');

4. Changes to doku.css (in lib/tpl/argon/assets/csdoku.css'') * Update line 657 from <code css>.col-md-auto, .col-md-12, .col-md-11, .col-md-10, .col-md-9, .col-md-8, .col-md-7, .col-md-6, .col-md-5, .col-md-4, .col-md-3, .col-md-2, .col-md-1, .col-sm,</code> to <code css>.col-md-auto, .col-md-12, .col-md-115, .col-md-11, .col-md-10, .col-md-9, .col-md-8, .col-md-7, .col-md-6, .col-md-5, .col-md-4, .col-md-3, .col-md-2, .col-md-1, .col-sm,</code> * Add <code css>.col-md-115 { flex: 0 0 97.5%; max-width: 97.5%; }</code> after line 1183 (after the closing brace).
