lingotek 7.x-5.04

This release fixes two bugs with the 7x.-5.03 release and adds an optimization for handling translation on large Drupal sites. The changes since 7.x-5.03:

#2213837 by lsolesen: fixed the order of title field and field-language preprocessing, preventing titles from disappearing.
#2213811 by lsolesen: fixed parameters passed to comment-related field function; changed a few more comment-specific behaviors to run only on condition of the comment module being enabled; removed dependency on comment module during setup to fix entity field query exception.
by shawn_smiley: optimized settings page to use entity field query instead of entity load to help sites translating large numbers of entities.
