Title: look up tables for script blocks

Script blocks need to be able to write to and read from lookup tables. They already have access to other simple definitions lookup tables by using `definition('other definition').identify_by(:id, 8)` for example.

What's missing is the ability of the script block to create its own lookup table. I have a use case where I need exactly such behavior. In this commit I took the simplest approach to make it possible.
