Courriel-0.02

Changes for version 0.02 - 2011-06-04

Added all_parts_matching() method to Courriel class.
Added clone_without_attachments() method to Courriel class.
The Courriel::Part::Single attribute raw_content has been renamed as encoded_content.
The text_body_part() method is now called plain_body_part().
The add() and unshift() methods in Courriel::Headers now accept only one value.
Added Courriel::Headers->replace as a convenience method.
A header with attributes (like Content-Type) can escape values inside a quoted string, like value="foo \" bar". Courriel wasn't unescaping these values.
It is now possible to pass a Courriel::Disposition object explicitly when constructing a Courriel::Part::Single object. The docs said this was possible in 0.01, but the parameter was just ignored.
If a part is created with an explicit content_type and/or disposition object, the part's headers will be updated so that the Content-Type and Content-Disposition match the given object.
The boundary for a Multipart part and the boundary in its ContentType's attributes will always be the same.
All classes now use MooseX::StrictConstructor.
Some hacks to make it possible for Courriel to play nice with Email::Abstract.
Fixed some small doc errors.
