Submodules? #57
Description
We're depending on quite a number of third party code now; OpenLayers, jQuery, minidetector, and more. Documentation about authorship, licensing and versioning is not quite up to par. Could this be alleviated with a tidying where most of them were moved into git submodules? The main disadvantage of submodules is that git hasn't made them easy to work with; we already have quite a number of commits reverting changes to the submodule pointer for the wiki submodule f.ex. Some of these disadvantages have been described in this article, and a comment for the same article describes how it should be used.
