Allow multiple blanks for handles

Allows a blank permalink if from is blank.

What is your use case for allowing blank permalinks? It means this object now cannot be found by its permalink. Which is counter intuitive.

We've got a Travis CI problem on gems and ruby versions. I'll dig into that.

Rebase master to get #9 to fix CI.

My use case is for when the object is not yet "ready" for public consumption, and the from data, in this case, the event name, is not yet filled out.

I'm wondering if I'm more after the ability to explicitly just call "build_permalink` with parameters. I don't want to overly complicate the configuration of this module.

[kmcphillips]

Yeah. I think that's more what you're describing.

If you allow a blank then you have a non-unique value in the table. If your record is not "ready" yet, it still has an id.

It sounds more like what you want is to recalculate the permalink when the record is "ready" to match the configured values.
