Check for default export in es2015 files

[tanepiper]

When using ES2015 with Babel6, it appears you need to check for the default export when the react template is transpiled.

This adds a check to see if Component.default exists, if it does then it uses this instead to pass to React.createFactory

Thanks for creating a PR! I left a few minor comments inline. We'll need to add tests for this and figure out why TravisCI is failing.

[tanepiper]

@jedireza Tests are failing because you're testing against Hapi 11, which only supports node >4 now (see build https://travis-ci.org/jedireza/hapi-react-views/builds/89329509)

@jedireza FYI - Happy to help migrate this library through to ES2015 and ensure support for > Hapi 11 and Babel 6

@jedireza Changes reverted as per comments

I left a PR on your fork to update the readme. After you merge that, squash the commits into one and then we can merge. The final commit message could be something like hapi 11 + node 4 + better es6 support, but it's up to you.
