compiz-profile-setter: tool to update the current profile and use in systemd and Unity settings

Added a compiz-profile-setter tool that allows to change compiz profile, so we use this to set the right profile when starting unity and when the gsettings key has changed. So we can just toggle lowgfx profile on the fly by just doing gsettings set com.canonical.Unity lowgfx true|false (LP: #1668950) Approved by: Andrea Azzarone (bzr r4233)
