Gsea enhancements

As the software is almost perfect, there are few bugs and little need for enhancements.

Bugs found 3/15/2006 include:

1. Generate a report, go to "Other" section, look at parameters. Error, file cannot be found.
2. Started a pretty long analysis, killed it. It took a few minutes versus a few seconds. If that's expected, perhaps change message to say may take a few minutes.
3. Leading edge report brings up the gct files in a text editor rather than Excel; can't really read them in a text editor.
