Accordion Content/ Menu script updated to version 1.5:

//Version 1.5: June 20th, 08':
1) Adds new "onemustopen:true/false" parameter, which lets you set whether at least one header should be open at all times (so never all closed).

2) Changed cookie path to site wide for persistence feature

3) Fixed bug so "expandedindices" parameter in oninit(headers, expandedindices) returns empty array [] instead of [-1] when no expanded headers found
