[DONE] What happened to the linux installer

[calhaus]

Hi, so since last talk:
-I've added a intro menu with an option to show Release or Testing packages from sourceforge.
So in the future the app could be up to date also with testing releases (and people can use both).

Just be careful posting the packages in *gz. Most of them in sourceforge are in that format, but i saw some in Testing in *xz, and in Archive all the files are in *7z. I haven't seen how the program is decompressing the files yet, but i know its looking for files with names ending in "*img.gz", so i didn't add Archives to the installer and *xz files wont show up for now;
-Fixed one or two small bugs;
-And fixed the linux part that was unmounting every single drive instead of the chosen one.

I haven't yet updated git because i'll try to cross-compile it to 32bit and for M$ Windows. (Also i can't test the mac version for bugs...)
