Merge pull request #14 from coderhaoxin/master

Fixes template locals persisting between renders
Bump version

Includes fix for render calls unintentionally caching `locals`.
Tests should not have the server bind to a port
Add test for recursive object merging
Add own merge and clone function

Adds a merge function so that recursive objects are no longer merged at
full depth (thus overflowing the call stack). This also removes one
dependency from the project.
