Issue 2 filebrowser.theme.inc uses deprecated function create_function()

[nattywebdev]

Remove create_function();
Replace inline style for file/folder icon with class 'icon'

This fixes issue 2 related to deprecated php function create_function for php later than 7.2.
Taken from patches provided for Drupal version of the module and adapted for Backdrop - see:
https://www.drupal.org/project/filebrowser/issues/3061756

Also addresses separate issue related to display of file/folder icons: containing table cell (td) had width set as % and this is replaced by a class added to the cell.

Line 262 now corrected.

When showing a list of files and/or folders, clicking on any of the headings to sort doesn't work correctly. The display order changes, but it is hard to see what the order is - it's certainly not (say) alphabetical order of file or folder names. Same for Size and Date columns.

This is not a problem in the unpatched version, so the cause is my fix. I'd value any insight into the cause by @argiepiano ...

• although subsequent testing shows this doesn't allow correct sorting.

@nattywebdev it looks like your patch changes the assignment of $a and $b, which are used for comparison:

• Original: $a receives the value of $a[$field], or 0 if it's not set
• Your version: $a receives the value of $a->$field or 0 if it's not set. Since $a is an array (not an object), this will result in the new $a being assigned 0 always.

This is true for $b as well. While I haven't tried this myself, see if this solves your problem:

            $sorter = function ($a, $b) use ($field) {
              $a = isset($a[$field]) ? $a[$field] : 0;
              $b = isset($b[$field]) ? $b[$field] : 0;
              return $a-$b;
            };

and

            $sorter = function ($a, $b) use ($field) {
              $a = isset($a[$field]) ? $a[$field]  : '';
              $b = isset($b[$field]) ? $b[$field]: '';
              return -strcmp(backdrop_strtolower($a), backdrop_strtolower($b));
            };

I've made those changes and now the sorting works correctly. I've created another PR - or should it be an update to this one?

[argiepiano]

@nattywebdev it's better to keep pushing changes to the same PR rather than open a new PR.

At this point this is fine - you can go ahead and close this PR in favor of #6
