Languages, Robustness, Fixes, oh my!

I'm just going to copy my commit message. Also, I may have said I did stuff in the last commit, that I had actually done in a previous commit. Too much stuff:

• Fixed trn creation. AutoPaint is now a button.
• Language can now be set by the user. Added spanish.
• Added "Get Path..." menu option to show a dialog with the current BZ path.
• Added dialog for completing Auto Painting.
• If program cannot find BZ path via registry, asks user until users provides.
• Title no longer contains current BZ path.
• Added comments to each file, summarizing it's role and contents.
• Actions contains an AutoPainter ActionListener.
• Create no longer tries to Auto Paint. It now adds trn data from the user selected planet to the new trn.
• Edit will now launch the editor with a bzn if it exists. If it does not, it launches it with the trn.
• Utility can now write the current BZ path to the registry for future use.
• All files now have better error handling.

Oh, and besides English, Dutch is supported (thanks Goomba!), and I added Spanish as well (though, it's been a while, so please complain if I screwed up).
