Experimental Mageia support
Adding LinuxMint (handled as Ubuntu).
Loosen the zenity test.

During installs without X (mostly test ones) zenity --version
causes a lot of noise. Just check for existance instead, version
doesn't really matter anyway.
Handle /sbin:/usr/sbin required in PATH.

Some platforms besides Fedora requires adding /sbin and/or /usr/sbin
to PATH to find utils like ldconfig. Handle by probing in configure
and locking down PATH in Makefile.in.
configure: bad bug in test code.

Return value fromm pipeline is last påart. Sigh.
Use specific binary name for user installs.

To allow user installs in parallel with systre-wide installs rename
wrapper to 'my-spotify' to avoid conflicts.
configure: bugfix in spotify.desktop patching.
Makefile.in: desktop target overhaul, bugfixes
ubuntu: cope with unity features/bugs

unity doesn't parse shebang, requires explict '/bin/bash whatever'sh'.
Also, unity requires user desktop files to be 755.
