new short-code to embed code

[campoy]

Previously we were using the triple backtick to indicate code, copy pasting code into the post.

As @dpordomingo proposed I created a new short-code named code which given the highlighting language.

So we can replace sections like this one:

which is rendered as:

With a simple short code call:

{{% code "/post/c-on-bigquery/udf.js" javascript %}}

Which displays as:

Note that the parameters are positional and the highlight language is optional.
