Removing FSS from Infusion

[Justin Obara]

The Fluid Skinning System was deprecated in Infusion 1.5 and slated for removal from Infusion 2.0. http://issues.fluidproject.org/browse/FLUID-5469

We found that for the most part the components weren't using FSS. The plan is to use Foundation for demos and the like, but to keep the actual components free from a dependence on any given framework. However, FSS also provided a few extra handy features namely a css reset and base file, both adapted from YUI. Foundation relies on Normalize.css, which seems to be the popular choice for reducing browser inconsistencies.

Another issue is the set of themes that we have. These are really only used for the preferences framework and UI Options for the contrast themes. However, we already have copies of these in the preference framework. Ideally we'd replace all of these with a CSS preprocessor to construct the themes and make it easier for a user to generate their own.

Proposals:

1) I propose that we make use of Normalize.css in our components as well as demos and etc. 

2) I propose that we remove the themes from within the fss directory and just keep the ones that are in the preferences framework. Later we should re-implement the themes using a CSS preprocessor.

Thanks
