Provide link to 1.1 for Mac OS < 10.6
S4 - Minor
Currently, the download button at the top provides only direct download for MuseScore 1.2. In case a Mac user wants to download MuseScore, he will see that it's only compatible with 10.6+ Intel. We should still provide a link to 1.1 as that one was for 10.4+ Universal.
