Got rid of the 'nil for integer' error, but I think index.html has to be in the sources directory (journal/entry) to properly generate blog.articles
Got middleman-blog working for journal/

Because it either generates year/month/day/index.html
or journal/year-month-day-index/index.html urls, I'll have to
return to the previous workflow, the one I abandoned because it
was complicated. Now it is necessary.
Reimplemented 'complicated' workflow for /journal/ to allow for pretty links and the advantages of reverse-chronological lists, pagination, etc
Merge branch 'midblog' into devel

Conflicts:
	source/journal/index.html.haml
Removed source/journal/<files> left over after merge with midblog (tmp branch)
