Translateability of on_behalf and honor_block_title for contribution pages
As described here https://civicrm.stackexchange.com/questions/38441/how-do-i-translate-the-on-behalf-of-label/38442
Short version: those labels are customizable per contribution page and live in the civicrm_uf_join table as the 'module_data' field, but the interface doesn't give you the multilingual field options.
It looks like there's just some code somewhere that should identify these fields as translatable so that the little translator popup gets attached.
