Bug 15092: item type descriptions not showing in OPAC advsearch

Go to OPAC > Advanced Search
Tab 'Item type' only shows itemtype icons,
no descriptions. Descriptions must be shown
always

To test:
1) Go to OPAC > Advanced search
2) Check no descriptions for item types
Also check that, reloading the page, item types
shows in random order
3) Apply the patch
4) Check there are descriptions now
and order is by description

Followed test plan, works as expected.
