[Live-demo] Sahana Install - minor edits

[Brian Hamlin]

Hi All-

   the Sahana installl script had two weaknesses; a path to install the 
desktop icon and the delay when starting the browser...
So I have made a minor edit and checked it in.. Please take a moment to 
check, either from svn in a test environment, or when the next build is 
done in about 48 hours..

   best regards from Berkeley, California
    -Brian
