Fixed bugs, mostly related to editable text fields.

	* README: Made the contents of this file slightly helpful.

	* data/mime/nautilus.keys: Added an obscure MIME type that
	someone reported running into.

	* libnautilus-extensions/nautilus-entry.h,
	* libnautilus-extensions/nautilus-entry.c: New files. Define a
	subclass of GtkEntry (one-line text editing field) that fixes
	bugs and adds convenience functions.
	(nautilus_entry_key_press): Override key_press handler to treat
	the keypad Enter key the same as the other Enter key (in GtkEntry
	it inserts a "/r" into the text).
	(nautilus_entry_select_all): Select all text, and move the text
	cursor position to the end.
	(nautilus_entry_select_all_at_idle): Same, but do it at the next
	idle opportunity. Useful since nautilus_entry_select_all won't
	work right if called in a key_press signal handler.
	* libnautilus-extensions/Makefile.am: Build these two new files.

	* src/file-manager/fm-properties-window.c:
	(name_field_activate): New function, updates file name and
	selects all text.
	(create_properties_window): Make name_field be a NautilusEntry.
	This fixes half of bug 433 (Enter keys don't work properly in
	properties window). Also attach to "activate" signal and update
	name change then. This fixes other half of bug 433. Also start
	with name field selected & focused. This fixes bug 432 (properties
	window should appear with name text selected).
	(name_field_update_to_match_file): Only update the displayed text
	if the new name coming in is different. This was needed to make
	select-all-on-activate work.
	(name_field_done_editing): Don't accept empty string as name;
	silently revert back to original name.

	* src/nautilus-bookmarks-window.c:
	(create_bookmarks_window): Change name & uri text fields to
	NautilusEntry; this causes keypad Enter key to behave like other
	Enter key. Also connect to focus_in and activate signals.
	(update_bookmark_from_text): New function, extracted from
	on_text_field_focus_out_event.
	(on_text_field_focus_out_event): Deselect all text after updating
	bookmark.
	(on_text_field_focus_in_event): New function, select all text.
	(name_or_uri_field_activate): New function, update bookmark and
	select all text.

	* src/nautilus-location-bar.c:
	(nautilus_location_bar_initialize): Use NautilusEntry instead of
	GtkEntry. This makes keypad Enter act like other Enter in uri-entry
	field.

	* src/ntl-window-msgs.c:
	(nautilus_window_end_location_change_callback): Make "Nautilus can't
	handle this type of file" message mention (human-readable version of)
	file type.
