Move common template index.html and css files into "default" folder

[tigerclaw-az]

I noticed that each of the /template/* folders have almost the exact same CSS and the exact same index.html file. Can these be moved into /templates/default and inserted into the template being used during generation?

Then each template folder would only contain the necessary CSS required to overwrite the common styling.

They certainly could be moved. I've kept them separate up until now to keep each one encapsulated and dependency free - I didn't want changes to one to affect the others, the pdf rules in particular can be quite fiddly. Keeping them separate also makes the assetic build a little simpler with the phar system too (the phar script can make relative paths weird). But, now that we have more than 3 templates, it might be worth doing a little refactoring.

The asset collector does apply LESS to the styles, but I haven't yet updated the templates to take advantage of that. Perhaps it's time to make a few reusable components and extend a common set of rules and get the path stuff sorted out.

I'll leave this issue open and make a commit against it when I have a chance.
