Incompatible with subthemes

We had a case where we needed several subthemes for cti_flex. However the subthemes didn't get all the default stylesheets from the base theme.

This seemed to be a problem with using a path_to_theme() function when including the default styles, resulting that these styles were tried to be looked up from the subtheme directory where they weren't available. Changing path_to_theme() to drupal_get_path() seems to fix this issue.
