Allow explicit setting of markdown extensions

Browse source 
These additions are to make it easier to disable pygments or any other
extension the user may not want. In the previous version, these plugins are
hardcoded, but by making it a variable in the config, it is possible to not use
pygments or easily load extra markdown plugins if needed; you can have multiple
plugins in one virtual environment and have different configs load them as
needed.

In my `pelicanconf.py` I then have the following:

    MD_EXTENSIONS = ['extra', 'syntaxhighlighter']

where `syntaxhighlighter` is a custom markdown extension I am working on to use
syntax highlighter instead of pygments for code highlighting.
