ThemeKey calls obsolete Organic Groups function

Hello,

I believe line 250 of themekey_ui.module in 7.x-2.0,

if (module_exists('og') && !og_is_omitted_type($type)) {

needs to be updated. The function og_is_omitted_type(), which was defined in Organic Groups 6.x, seems not to be defined in Organic Groups 7.x. I noticed that the Spaces module tackled a nearly identical problem, and I think changing the aforementioned line to

if (module_exists('og') && variable_get('og_group_type_' . $type, 'omitted') != 'omitted') {

will solve the issue.

Thanks for ThemeKey!
