Removed jekPygments and choosing a cssPre

Jekyll will have Pygments enabled by default and since we will be
running libsass there's no need to ask for what kind of CSS
preprocessing you want to run. This is yet another update for issue
Removed the conditionals for markdown and pygment

By default we will run Redcarpet for the Markdown processing and
Pygments is enabled by default, no need for conditionals in the
_config.yml file in that case. Updates #16.
Removed the option for Markdown and leftover code

Since we won't be needing to chose markdown engines or Pygment this
code has been removed. See #15 and #16.
Removed Compass from Gruntfile.js
Removed all functionality for cssPreprocessors

This commit removes all the mentions of having to use different CSS
preprocessors throughout all the code. See issue #15 for more. Still
needs a lot more cleaning up. This will definitively make the generator
throw errors.
Removal of jekyllPygments from the codebase

With this commit all the code and variables for Pygments should be gone
and it now runs by default. This is a continuation of #16.
Update the CHANGELOG to reflect changes
Removed all functionality and conditionals

This is a major refactoring of the code that should result in no
mention of CSS preprocessors or JavaScript preprocessors. Still more
cleanup required. See #18, #17.
One } too many and removed some leftovers

Had one if statement in the Gruntfile for autoprefixer, this should
now be clean.
Made googleAnalytics included by default
Renamed readme.md to README.md, consistency yay
