Added new r14-xdg-update shell script to handle R14 XDG compliance updates.
Numerous improvements from original snippets originally inserted in starttde. Added migratekde3 shell script to migrate existing KDE3 profiles to Trinity profiles, thereby closing bug report 709.

+#
+# Overall, this script works quite nicely, but please help to
+# make this script more robust!
+
+# Testers: need help to ensure this script remains POSIX compliant.
+# Some distros do not use bash as a default shell.
+
+#===============================================================
+# This is a modest attempt to migrate a KDE3 profile to Trinity.
+# If $HOME/.trinity exists then skip this one-time migration.
+
+# Can this script be run from within starttde?
+# Challenge: to run this script from within starttde requires
+# graphical dialog boxes. When is the underlying TDE system
+# sufficiently operational in the starttde script to use KDialog?
+# If KDialog is unavailable then that leaves xmessage, which is
+# ugly although possibly adequate.
+
+# If KDialog is unavailable until after $HOME/.trinity exists, such
+# as after running KPersonalizer, then this script will not help.
+# Also, KPersonalizer automatically creates a skeleton profile directory
+# when launched, as does some command line tools such as kconf_update.
+#
+# Additionally, this script was written mainly from a command line
+# login perspective. This script and concept needs testing and
+# improvements to support graphical login systems.
+
+#===============================================================
+# Known Quirks:
+# When testing the same user account between two different systems, such
+# as a real and virtual machine or two different physical machines,
+# after a migration KMix is always muted because the sound devices differ.
+
+# Not sure, but forced window sizes saved in kwinrulesc seem to break after
+# a migration.
+#===============================================================
