Create cool-old-term.spec

Add a spec file to create RPM packages of cool-old-term.
Verified to work with both Fedora 20 and openSUSE Factory. Support for other RPM-based distros (Mageia comes to mind) is as easy as adding additional (Build)Requires conditions.
Update cool-old-term.spec

Name fix
Update and rename cool-old-term.spec to rpm/cool-old-term.spec

Put specfile in a subdirectory and add a line that was missing before
Rename rpm/cool-old-term.spec to packaging/rpm/cool-old-term.spec
Merge pull request #55 from KAMiKAZOW/patch-1
