WIP: a thought bubble about how to browse column header labels from user prefs
WIP: strings and rubber bands - configurable browse for accessions
removed unused acquisition_type_sort declarations
move preferences from system menu to user menu
removed column label preferences
tidying up defaults form
moved the browse column adding code to a def in the search helper
extended to resource browse
translate column names in defaults form
show inherited default values in selects
added the ability to override a column to make it not display
extend browse preferences to digital object browse
added reindex migration
fixed test after preferences link moved
fixed two bugs - getting current preferences when there is no repo_id in the session, and reliably getting inherited defaults when the parent level preferences record doesn't exist
added a selenium test for configuring browse columns
Merge pull request #744 from hudmol/configurable-browse
