* thunar-vfs/thunar-vfs-uri.{c,h}: Add support for the 'computer://'
	  URI.
	* thunar/thunar-trash-folder.c, thunar/thunar-local-folder.c,
	  thunar/thunar-folder.c: Drop the GObject properties, as they are
	  mostly useless here.
	* thunar/main.c(main): Use thunar_vfs_uri_new() for the optional
	  command line parameter to be able to open arbitrary URIs from the
	  command line.
	* thunar/Makefile.am: Add new class ThunarComputerFolder to the build
	  framework.
	* thunar/thunar-computer-folder.{c,h}: Add ThunarComputerFolder class,
	  which implements the 'computer:' URI. This vfolder is the root of all
	  other root folders, currently 'file:/' and 'trash:'.
	* thunar/thunar-file.{c,h}, thunar/thunar-folder.c,
	  thunar/thunar-list-model.c, thunar/thunar-local-file.c,
	  thunar/thunar-local-folder.c, thunar/thunar-statusbar.c,
	  thunar/thunar-trash-file.c, thunar/thunar-trash-folder.c: Add support
	  for the 'computer:' vfolder as overall root node. Rearrange the
	  get_size() method to be able to support objects for which no size
	  is known, currently vfolders and directories in general. The virtual
	  get_mime_info() method now automatically takes a reference on the
	  returned object for the caller.
