Including default configs for java.jdbc and hiccup functions that used to have many incorrect :wrong-arity warings.
so that the files in that directory are not included by default when I use Eastwood to lint itself. Those files are already linted every time I do 'lein test', and contain many warnings that I don't usually want to see when linting Eastwood.
This is an attempt to allow Eastwood to lint more projects, even if they depend upon a version of a project incompatible with the one that Eastwood itself depends upon. Now they will be in separate namespaces (as long as no linted project uses eastwood as its first namespace segment).
