Change folder structure of smpl create

[saschat]

How about putting all source files in a src directory and change Application.hs to MyAppName.hs within the src directory? Or app instead of src is also a good option.

For example smpl create test_blog would create the following structure:

layouts/
views/
src/TestBlog/Common.hs
src/TestBlog.hs
Main.hs
test_blog.cabal
