Generate userInterest and randomize tag scores

* Wanted to have different values for each tag per user
* Changed tags script to generate an arbitrary number of tags, which can be used to reduce the number of tags attached to companies...but I want to see all of them for now, so I am still taking all and not a subset (for example, you can pass in '10' on line 178)
* Added script at end so some users will have their userInterest on matches set to test that functionality
