Security patch for tempfile vulnerability CVE-2005-3343

This commit was manufactured by cvs2svn to create tag 'REL-4-1'.

If the newDiffDialog is canceled before real startup, just exit.

Update the MacOSX packager, re-write the changelog, and add some test files.

Expanded the newDiffDialog so it can be used for all the options. Separated
parsing the command line from handling the options from the dialog. Made a usage message for command line.

New option for headings for file titles. Other misc patches.

g(debug) enables some tracing output.

Floating tooltips for the toolbar items. That frees the status bar for "4 of 56 diffs" info.

Removed a small amount of dead code.

Patch 1106205 added Clearcase support

Patch 981930 -L command line option - allows you to control the labels
above the diff file panes

tkdiff -L <label for left file> ....
tkdiff -L <label for left file> -L <label for right file> ...

Patch 1068200 Better subversion support
Subversion also keeps a unmodified copy of the files
around, so if rev is unspecified, or is BASE, diff
against that file instead of running "svn cat -rBASE"
which currently requires network access
