Needs update to PhoneGap 1.5

[ns-1m]

I think HelloPhoneGap needs updating to 1.5 especially that we could not find any PhoneGap1.3 version anymore.

No download for PhoneGap 1.3 library that goes with this example at the moment.

Probably you need to git clone PhoneGap 1.5 when you update this demo so it will not be obsolete when PhoneGap updates to another version again.

Thanks.
