v0.2.0

This release follows the ArchieML spec recommendation dated 23 April 2015.

• Clarification to note :skip blocks, when placed inside a multi-line value, should break up the value, causing only the first line of the value to be stored.
• Change to how arrays that are defined multiple times are handled. Instead of "reopening" the original array, secondary definitions should replace previous definitions, making duplicate-key behavior of arrays match that of key/value pairs.
• Bugfix (thanks @kevinschaul!) for overwriting strings with objects
