Suggested changes to the Quickstart Guide

1) It's freeware. Alcohol 120% is trialware, and will only work for a limited time before you need to pay for it.
2) No bundled adware. Alcohol installs a nasty toolbar in your browser as part of the installation process.
3) It's much simpler to use. With ImgBurn it's only a matter of install, click a button, and you're done. But Alcohol requires a restart, after which it installs an extra virtual drive or two on your PC (which is unnecessary for the purposes of RPCS3), and the software itself is significantly more complicated to use.

Good points!
Even if the adware can be avoided somewhat easily, it is just simply better to not have the need to avoid it. It isn't too hard to get rid of the virtural drives, but yeah, same reason as stated earlier applies here. Generally, the simpler the steps are, the better.
