Update _posts (our events) with what happened

[gnarlinsky]

Here is what I can remember off the top of my head... None of these are complete, of course:

• May 9th general meeting: Walked through the workflow of updating the Py-CU website, including version controlling with git and running locally with Jekyll.
• May 23rd general meeting: git and Github; gollum; Ruby; OS X difficulties with both of those
• May 28 hack session: Hacking the electronic lock box
• June 4 hack session: Twitter Bootstrap interface generators; Jekyll and Liquid
• June 7 general meeting: Cython, Python and Physics (turns out 44% of us at the meeting do research in Physics), North Korea.

Note: I updated the meetup notes from 2013-07-19 (last night) in pull request #7.

Someone should please review :)
