Tk/JComboBox version 1.14

CHANGES OVERVIEW: (details below)

Maintenance release to correct memory leak, and minor documentation problems.

OVERVIEW

JComboBox is a Combo Box implementation that combines several features of the various Combo Box implementations available for Perl/Tk and attempts to provide a solution that should cover the majority of your Combo Box needs. The implementation tends to skew somewhat towards the Java and Win32 implementation of a Combo Box more than the Motif one.

Thanks to everyone who has contributed suggestions, code, and any other feedback. I'm not always able to incorporate that feedback, but I've always found it to be helpful. I hope this widget continues to be useful.

1.14 Maintenance/Bug Fixes: (No new features)

Issue: bdz (on clptk) reported a problem when choices arrayref contained a selected param for one of the entries (in editable mode). The problem was due to choices method being called prior to the widget options being defined in ConfigSpecs within the Populate method.
- Resolution: Moved choices call to after the ConfigSpecs definition; tested. Seems fine.
Issue: Benoît Vincente reported obscure problem that indicated problems with JComboBox::Tie. After investigation, it appears that when the master JComboBox is destroyed, it is not automatically removed the tie. This problem is trickier than it appears, partly because of the implementation of Tk::JComboBox::Tie and partly because of how widget destruction is done in Perl/Tk.
- Resolution: Added a few lines to check all JComboBox listeners, to see if they still existed prior to sending event notification to each. If a listener no longer exists, it is removed, and the reference is undef'd. This appears to fix the case Benoît reported (which should rarely occur in any case).
Minor revisions to JComboBox pod.
