Add more docs to `Time` module

[dbrgn]

Elm beginner here.

Initially I did not really understand how inSeconds etc work, so I tried to add some docs.

I hope the changes are correct. I did not manage to generate a preview of the docs. This is what I tried:

$ cd path/to/core
$ elm-make --docs=docs.json

...but the docs.json file is empty, so it can't be fed to http://package.elm-lang.org/help/docs-preview.

This will be moving to https://github.com/elm-lang/time which does things in a much clearer way. It will be out with the next release of Elm, and I hope it clarifies things with a bunch of new docs in the README and such.
