Feedback from Jose
Get CSS concatenation working

Having trouble naming the concatenated output file 'css/site.css',
however. This gets Hakyll into a cycle, where it claims that
'css/site.css' depends on 'css/site.css'.
Put css in css/
Put date in metadata, not filename
Create homepage
Remove unused image
Rewrite homepage URLs to not have index.html
First code-wrapping
Add title field to homepage
Merge branch 'hakyll'
