Title: new PostgreSql entity impl using chef

new PostgreSql entity impl using chef, and changes elsewhere to make this nicer:

* new EffectorStartableImpl which is a BasicStartable who expects effectors defined as static constants (not methods);
* restructure chef live tests (and other live tests);
* introduce Jsonya convenience for building json objects;
* add multi-line cat-to-pipe BashCommand
