Configure forking context with conf file

[labianchin]

Currently forking can be disabled with environment variable FLO_FORKING=false.

I would be great to have this configuration in typesafe config, like defining something in reference.conf:

flo.forkingEnabled=true
flo.forkingEnalbed=${?FLO_FORKING_ENABLED}

How about also disabling it by default? Seems to be the cause of a number of bugs lately: #100 #101 #102.

Object serialization and JVM forking is tricky, so we should let ForkingContext accumulate some mileage before being enabled by default.

Merged #104 now. Seems it missed 0.2.11 though.

This has been released. Closing.
