Adding more Sassy text options.

A friend's artwork was ripped off recently, and that inspired me to add some Sassy sayings like "Don't steal from artists" to the Sassy Watermark Maker.

ToDo: with more pre-written text options, I need to improve the randomness and selection functions.

I'm also working on a fun new feature...can't say anything about it yet, but I hope folks will enjoy it.
