Merge pull request #29 (1) "code in __init__.py is evil"

From: https://github.com/kennethreitz/pystache/commit/8ca7408f6948f7a7214897d4a31b0a3aabaf8216
Into: issue_29

Moves code out of __init__.py into its own module.

Changes from the original request:

 * Called the new module init.py instead of core.py.
 * Added a comment inside __init__.py.
 * Used editor-agnostic encoding line.
 * Fixed import line in view.py since nosetests was breaking.
