merge -r17289 from trunk to 2.4: batch manager improvements/fixes:

- when refreshing photo set, start is set to 0 (otherwise if the new set is smaller that start, it looks like it is empty)
- correct positioning of thumbnails (width/height) is done in template instead of javascript (immediate instead on ready + no reflows)
- less space lost on batch manager page
- fix wrong page title in batch manager because of global variable $title overriden
- fix language keys in element_set_ranks (capital/lowercase issue)
