Replace page now with now function

[npwalker]

This PR include #59 because that seems like a good idea and changes the same code.

This gets rid of the following deprecation message during build.

WARNING: Page's Now is deprecated and will be removed in a future release. Use now (the template func).

Another vote here to merge this pull request! Hyde-X no longer works with Hugo 0.35, and this pull request fixes it. Thanks @npwalker.

Here was my error message, in case anyone googles it in the future:
