New Download Section and PJ64 bin

[zilmar]

Hi All, I have been busy working on a new download section that will allow you to download all the files in one package, this is now up and should be working. The existing beta download section is still there.
I have also updated pj64 with re-doing a lot of how the rom browser refreshed and displayed roms, as well as adding 7z support in to the rom browser.
Enjoy
