Allow user to provide Liquid variables via sbt

[tpolecat]

It would be nice if I could say something like

micrositeVariables := Map(
  "version" -> version.value,
  "org"     -> organization.value
)

or something like this, and push them forward into Jekyll so that I could say {{microsite.version}} in my markdown … keeping versions correct in doc is always a problem. A good default map might include version, name, description, and org.

You may have something like this in mind already. If not maybe I can hack it up? wdyt?

Sounds good. Thanks!

We have to make a decision around this, Lars commented a different alternative: providing the ability to create your own jekyll configuration and put it as a resource: #43

This is very useful and is present in other tools like Paradox through the @var directive and the paradoxProperties setting. I'd rather not to leave SBT to configure these properties.
