uap-scala 0.2.0

This release includes four changes: it updates uap-core to 14e2c8d7 (#22), updates the SnakeYAML version from 1.10 to 1.18 (#18), removes the Twitter Util util-collection dependency by replacing LruMap with a simple LinkedHashMap-based LRU cache (#18), and changes four methods (#21):

1. Parser.get and CachingParser.get have been renamed to default.
2. Parser.create and CachingParser.create are now fromInputStream and return the parser in a Try in order to protect against runtime exceptions from malformed inputs.

The get and create methods have been deprecated and will remain available until 0.3.0.

This release is cross-published for Scala 2.10, 2.11, and 2.12 (#18 and #20).
