Changed Python hour posts so that date is at of title.
Removed permalink and changed data format to just date (no time+TZ) for post metadata on index page.
Style changes to metadata line.

Changes include using `/` as a separator and comma between tags.
Updated tags and added links to 2014 July 28 Python Hour notes.
Summary update to tutorial notebooks.
Change "Blogroll" to "Useful Links" & added "Social" on sidebar. Added "Fork me on Github" badge.
Removed "More..." buttons and moved article link to article title.
Attempt to make column width smaller.

I changed both min-width and max-width.  Trying out various options, the widths didn't seem correct in the Chrome Developer Tools.  I'll have to figure out how the various widths interact to create the final product.
Added TODO to README.md
