[Patch] fix bug #8487: read-only status not shown in title bar

Hi,

I have fixed bug #8487: read-only status not shown in title bar
http://bugzilla.abisource.com/show_bug.cgi?id=8487

Patch and fix screenshot are attached on that bug. Can someone help me
to have a review? thanks

Investigation:
  Only Windows don't show read-only status in title bar. the reason
is that in Window, there is not function to read user-permission.

Solution:
  I add some code to read user-permission and fix it.
