Suggestion patch for this feature

This patch is tested in my local buildings. 
It includes two major modification:
1. add one new cmd line option: --daemon, which can be used in first startup, to enable nautilus run as a daemon without any window
2. add one new gconf key: apps/nautilus/preferences/daemon_enable, to enable nautilus to run with both '--no-desktop' and '--no-default-window' without quit instantly.
In another word, 'nautilus --daemon' is mostly equal 'nautilus --no-desktop --no-default-window' with gconf/daemon_enabel being TRUE.

The following cases are tested:
1. case: before any nautilus instance exist, start nautilus with '--daemon'
 expect: run in background without any window

2. case: before any nautilus instance exist, start nautilus with '--no-desktop --no-default-window', with gconf/preferences/daemon_enable being TRUE
 expect: run in background without any window

3. case: after nautilus run with daemon mode, run 'nautilus --quit'
 expect: all nautilus windows and daemon should be killed

4. case: after nautilus run with daemon mode (with automount preference TRUE), plugin usb storage device
 expect: a file explorer window popup and show the content of usb storage

5. case: with nautilus running with any mode, start nautilus with any acceptable options
 expect: nautilus should not create new instance, send request msg to exist instance and quit
