rakefile for creating a new post

Code derived from https://github.com/lmullen/lincolnmullen.com
rename task
change filename extension from .markdown to .md
Set yaml the way I like

layout
comments
title
date
tags
Write straight to posts directory
Task accepts arguments
open new post file in Sublime Text
update task

Updates the most recently-edited post to the correct date

1. Changes the “date:” field in the YAML header
2. Performs git mv to change the filename
Comment for clarification
implement git mv portion
clarifying spaces
Merge branch 'rake'
