Version 2.0.0 Release candidate 1

Available at Clojars

Breaking changes:

• In version 1.x, Drift would pass any unknown args to the init function. Now Drift requires separating args for the init function and args to Drift's tasks by a double dash e.g.: lein migrate -v 5 -- these args are passed to my init function

Fixes:

• Java 9+ compatibility
• Unknown args now fails the task and prints usage
• Added ability to redefine config-fn-symbol in lein project
• Migrate directories containing spaces and Unicode characters now work
