Resolves Issue RomRaider#23
 - Compare now passes the table directly instead of using the clipboard
to transfer data.
Add HTMLInfoPanel as first panel in installer sequence.  This warns the user about the necessity of a 32-bit JRE and points to the RomRaider Troubleshooting forum.
Updates to build instructions:
- Clarification that "all" target should be used rather than manual selection of all
- Instructions for developing using a 64-bit version of Eclipse.
- Cleanup, with some reformatting.  It's still not entirely consistent. If it's going to be used as a basis for the Getting Started page on romraider.com, it should be redone in the proper markup
- Add instructions for contributing back to the master git repository. These are likely light on detail, but the basics are there.

- Check if the component is a JSplitPane before trying to cast as one
