4getmoz version 1.7.4

I just released version 1.7.4 of 4getmoz which is a Mozilla and Phoenix download script for 4NT users. The 4getmoz script provides all 4NT users with an easy and fast way to download and install the nightly build of both Mozilla and Phoenix.

What's new:
- spelling
- adding save plugins folder option. Use saveplug as parameter
- minor bug fixes
