r1432: - Move the various Gtk-specific parts from the registry code into a directory gtk/

- Move common "Samba-Gtk" code into gtk/common/ ("Connect to RPC pipe"-dialog, etc)
- Add a new utility 'gwcrontab' that can currently list, delete and add 'atsvc' jobs. It still displays times and dates as integers though, will fix that later.

Some screenshots available at:
 http://samba.org/~jelmer/gwcrontab/
(This used to be commit d321cf20f1f0ff33603b013c26d370669f255868)

+This directory contains files for SMB-related Gtk Widgets 
+and helper functions and utilities (frontends) for various SMB 
+things.
+
+Common code at the moment:
+GtkRpcBindingDialog - Gtk Dialog Window for obtaining user credentials and a RPC binding string
+gtk_show_werror() - Show dialog box with a WERROR
+gtk_show_nterror() - Show dialog box with a NTSTATUS
+create_gtk_samba_about() - Shows about Window
+
+Utilities:
+gregedit - Gtk+ Registry Editor (RPC, NT4 files, W95 files, GConf)
+gwcrontab - View and edit 'cron/at'-like jobs using the atsvc service (needs a better name)
+
+Ideas for future utilities:
+- SAM editor
+- Eventlog viewer
