* thunar/thunar-standard-view.c
	  (thunar_standard_view_merge_custom_actions): Fix typo.
	* thunarx/thunarx-private.{c,h}, thunarx/thunarx-menu-provider.c,
	  thunarx/Makefile.am, thunarx/thunarx-property-page-provider.c: Add
	  helper function thunarx_object_list_take_reference(), so we don't
	  need to repeat the same code again and again.
	* thunar/thunar-window.c(action_entries): Add ... to the Preferences
	  action, since it opens a dialog. Use "e" as mnemonic, as "P" is
	  already used by "Paste".
	* thunar/thunar-standard-view.c(action_entries): Add ... to the Select
	  by Pattern action, since it opens a dialog.
	* thunar/thunar-preferences-dialog.c: Close preferences dialog on Esc
	  key press.
	* thunarx/thunarx-preferences-provider.{c,h}, thunarx/thunarx.h,
	  thunarx/thunarx.symbols, thunarx/Makefile.am: Add new interface
	  ThunarxPreferencesProvider, which can be implemented to add custom
	  actions to the preferences section of the "Edit" menu.
	* thunar/thunar-window-ui.xml, thunar/thunar-window.c: Query custom
	  preferences actions from the installed providers and add them to the
	  preferences section of the "Edit" menu. Actions are loaded in an idle
	  source to not delay folder loading when opening a new window, even if
	  a lot of preferences providers are installed.
	* docs/reference/thunarx/: Update the thunarx reference documentation.
	* thunar-uca/, configure.in.in, Makefile.am: Import the thunar-uca
	  module, which provides advanced users with an easy way to add custom
	  actions to Thunar's context menus. With this extension in place
	  there's no longer a need to add support G-Scripts (except maybe an
	  importer for thunar-uca).
	* po/POTFILES.in: Add new translatable files.
	* po/: Merge new strings.
	* examples/tex-open-terminal/README: Add note to use thunar-uca, and
	  consider the tex-open-terminal as example for extension writers.
