Added test for set via literal
Merge branch 'dev' of github.com:christav/envconf into set-via-object-literal
Added ability to set values via object literal.

Can now call 'c.set({key: value, key:value})' to set a bunch of stuff
at once. Passing a function as a value is the same as using c.setFunc.

Also updated package.json for updated github location.
relaxing versions for test tools
Fixed merge conflicts
Updated docs
