Simplify dependencies

[tballison]

We currently have jackson-databind in at least 4 jars. We should try to be more parsimonious with dependencies. Not sure how best to do this. For example, can we create a lib/common directory and put jackson-databind in there and strip it out of tika-serialization and various other jars?

Some ideas...
