Extract local path logic and add tests. (vuejs#341)

* Extract local path logic and add tests.
* Add appveyor to run test on Windows.

* Fix weird race issues.

- Always pass call callback function on generate.
- Previously tests were randomly failing when running few times in a row.

* Windows will scandir for template.
* Add missing dev dependencies.
* Node v4 will get npm v2 which fails on windows. - update readme
