* thunar/thunar-enum-types.{c,h}, thunar/thunar-list-model.c,
	  thunar/thunar-path-entry.c: Rename THUNAR_COLUMN_REAL_NAME to
	  THUNAR_COLUMN_FILE_NAME.
	* thunar/thunar-enum-types.{c,h}, thunar/thunar-list-model.c: Add new
	  list model columns THUNAR_COLUMN_GROUP and THUNAR_COLUMN_OWNER.
	* thunar/thunar-enum-types.{c,h}: Divide ThunarColumns into visible and
	  special columns.
	* thunar/thunar-text-renderer.c(thunar_text_renderer_get_size): Improve
	  guessing the required width for text columns.
	* thunar/thunar-text-renderer.c(thunar_text_renderer_set_widget): Set
	  fixed height for the text render.
	* thunar/thunar-preferences.c, docs/README.thunarrc: Add preferences for
	  the configurable detailed list view columns. Bug #1351.
	* thunar/thunar-column-editor.{c,h}, thunar/thunar-column-model.{c,h},
	  thunar/Makefile.am: Import ThunarColumnModel and ThunarColumnEditor
	  classes. The ThunarColumnModel class handles the order, visibility and
	  fixed widths of columns. The ThunarColumnEditor class provides a
	  dialog to configure the ThunarColumnModel. Bug #1351.
	* thunar/thunar-details-view.{c,h}, thunar/thunar-details-view-ui.xml,
	  thunar/Makefile.am: Use column order and visibility from the
	  ThunarColumnOrder. Add "Configure Columns..." menu item to "View",
	  which pops up the ThunarColumnEditor. For fixed column mode, we use
	  the fixed height mode provided by GtkTreeView, which speeds up the
	  detailed list view a lot, esp. with older Pango version. Bug #1351.
	* po/POTFILES.in: Add new files here.
	* po/Thunar.pot, po/*.po: Merge new strings.
	* po/de.po: Update the german translations.
