Sorted out scss exclude

Realised that exclude doesn't work with paths. It just expects a single directory or filename.
So, even if the directory is nested in a directory tree, it ignores it.

So, that easily allow me to remove scss folder that was in the assets folder.

TODO : How to compile/minimise the JS, and exclude the uncompiled JS.
