Provide official AppImage builds for Linux

Please provide PowerShell in the AppImage format for Linux.

AppImage is a packaging format for Linux that lets users download one single file, set the executable bit and run the application (here: PowerShell). Unlike other solutions, no special runtime infrastructure must be installed on the target system(s).

An unofficial PowerShell AppImage has been available on https://bintray.com/probono/AppImages/PowerShell#files. It has been tested on

• CentOS-7.0-1406-x86_64-GnomeLive.iso
• CentOS-7-x86_64-LiveGNOME-1511.iso
• Chromixium-1.5-amd64.iso
• Fedora-Live-Workstation-x86_64-22-3.iso
• Fedora-Live-Workstation-x86_64-23-10.iso
• SL-72-x86_64-2016-02-03-LiveDVDgnome.iso
• debian-live-8.0.0-amd64-xfce-desktop+nonfree.iso
• debian-live-8.4.0-amd64-gnome-desktop.iso
• elementary_OS_0.3_freya_amd64.iso
• kali-linux-2.0-amd64.iso

• kubuntu-14.04.4-desktop-amd64.iso
• kubuntu-15.04-desktop-amd64.iso
• kubuntu-16.04-desktop-amd64.iso
• linuxmint-17.3-cinnamon-64bit.iso
• neon-devedition-gitunstable-20160814-0806-amd64.iso

• xubuntu-16.04-desktop-amd64.iso

To try it, run

PS="PowerShell-6.0.0.alpha.9-x86_64.AppImage"
wget -c "https://bintray.com/probono/AppImages/download_file?file_path=$PS" -O "$PS"
chmod a+x "$PS"
./"$PS"

@TravisEz13 mentioned that the AppImage works for him and @andschwa mentioned that he likes the idea of having one format for all Linux distributions.

The script that generated the AppImage is here. Feel free to use it, e.g. as part of the automated Travis CI build process. I am happy to help.

PowerShell-6.0.0.alpha.9-x86_64.AppImage works fine on Slackware64-14.2 as well.
