Release Name: 1.4.0

Notes:
An extensible Ruby wrapper for Atom and RSS parsers.

Feed normalizer wraps various RSS and Atom parsers, and returns a single unified
object graph, regardless of the underlying feed format.


Changes:
1.4.0

 * Support content:encoded. Accessible via Entry#content.
 * Support categories. Accessible via Entry#categories.
 * Introduces a new parsing feature 'loose parsing'. Use :loose => true
   when parsing if the required output should retain extra data, rather
   than drop it in the interests of 'lowest common denomiator' normalization.
   Currently affects how categories works. See the documentation in
   FeedNormalizer#parse for more details.
