It is useful to be able to add a random seed. This will make it possible to use random lists which changes content in a controllable fashion.

In addition a call to srand() is changed to mt_srand()

A typical call can be extended with "randomseed={{#time:Ymd}}" to make a dynamic list change once each day, or like "randomseed={{#time:YW}}" to change it once a week.

Note that the page with the list still needs to be purged or updated in some other fashion.
