moved member post feed to HAML
Merge branch 'dev' into rss-markdown
some improvements to the HAML RSS
Escaped_Markdown HAML filter, for use in RSS.

I tried to do this using Haml::Filters::Markdown so it would be
independent of our Markdown renderer, but I couldn't get
Haml::Filters::Markdown.render to work programmatically - whatever I
did, it returned its input unchanged. So I hardcoded a dependence on
bluecloth.
Tests for Haml::Filters::EscapedMarkdown.
Test for expanded-markdown rendering.
Converted Posts RSS to HAML
Removed redundant @recent_posts instance variable

Not required, as we have pagination by default
Converting crops RSS to HAML

Added spec for crops RSS

Removed redundant @new_crops instance variable (not needed as we now
have pagination).
Replaced plantings RSS with HAML

Removed the redundant @recent_plantings variable and added pagination
removed unwanted @recent_comments, replaced w pagination
Added RSS feed for all comments
Added RSS feed for comments on a single post
Reordered comments: they are now DESC by default

Added scope "post_order" to order them ASC for display on post page.
Also tweaked post/comment views a bit.
