[SR-Users] 2 rollover contacts per user

[Krishna Kurapati]

Thanks Daniel for the suggestions. To make the script manageable, I am
thinking of implementing last option.
Have another flag to "save". May be 0x8?

We will still use max_contacts = 2 in mod params.
And when the save("location", "0x08") is called, the oldest contact is
removed and the new contact is
added. This can apply to any number of max_contacts...

This way everything else remains the same.
