* Add compression controls (#417)

* Add compression controls

Add configuration options to allow for a compression algorithm of `none` to disable compression altogether.  Also an option to change the point in the LSM tree when compression is applied.

* Handle configurable defaults consistently

Move them into leveled.hrl.  This forces double-definitions to be resolved.

There are some other constants in leveled_bookie that are relevant outside of leveled_bookie.  These are all now in the non-configurable startup defaults section.

* Clarify referred-to default is OTP not leveled

* Update leveled_bookie.erl

Handle xref issue with eunit include
