Modified files:
        pidgin/gtkutils.c

ChangeLog: 

Install a custom GtkIMHtml procol handler for the "file://" type which
opens the file by default, and also has a menu for opening the file or the
directory that contains it.

Someone should figure out the correct handle to use for purple_notify_error
because GtkIMHtml doesn't close them (that I can see).

Fixes #8254.
