Replace strtolower by its drupal_* equivalent

Would also need addressing in:

root@unicron /v/w/d/5/panels# grep -Rn 'strtolower' *

content_types/node_form.inc:290:  .., '@type' => strtolower($choices[$conf['id']]['title'])));
content_types/term_list.inc:124:  ... '@type' => strtolower($choices[$options[$conf['type']]])));
panels_mini/panels_mini.module:256:  if (strtolower($ts['sort']) == 'desc') {
panels_page/panels_page.admin.inc:72:  if (strtolower($ts['sort']) == 'desc') {
panels_views/panels_views.module:159:  if (strtolower($ts['sort']) == 'desc') {

Committed; also found a few more and fixed em. Btw, Pancho, could you make sure to make the patches using Unified/Workspace root, rather than project root? I have to go in and manually edit them, since I also use eclipse and it picks up on the root you have (panels/...) and it doesn't correspond to my set up - I have a full drupal 5 multisite install for all my dev on d5, all of which is under svn; I then also keep certain specific modules directories under CVS control, but only the directories themselves.

Anyway, thanks!
