use Perl

I *finally* got around to working on both Tk::PopEntry and Tk::LabPopEntry and got them uploaded to CPAN. My Tk is kinda rusty, so I was worried that I wouldn't be able to figure out how to solve the "scroll to right" bug that someone had pointed out.

So, I pulled out my trusty Mastering Perl/Tk (shameless plug) and solved it in one line in about 8 minutes worth of research. I also fixed some embarrassing "unitialized" errors that I definitely don't remember when I last tested these modules, though that was in the 5.00503 days. Either I wasn't using the -w switch (seems unlikely) or something changed between 5.5 and 5.6 to warrant the warning. Well, it needed fixing in any case, so no big deal. Just kinda confusing is all.

I'm trying to decide what I want to work on next. I could add the pack and unpack methods to Set::String. I could write that Sys::Mailhost module I mentioned a while back in c.l.p.mod. So many ideas...
