Improve usage outside IPython

[Hugovdberg]

Build upon #46 to allow injecting globals when used outside IPython. If you are willing to accept this signature change then it is probably best to include some info in the documentation for usage outside Jupyter and IPython.

Thanks a lot for the PR! I am a bit swamped right now due to end-of-the-semester grading, but at first glance, it looks great! I will take another look next week and incorporate it in the docs (and make a minor new version release so that it can be used).

This looks good to me, thanks again for the PR!

Regarding the documentation example, I just added an example to the README file

• It is now possible to inject globals when used outside IPython (#80, via contribution by
  Hugo Lapré). For example, version numbers of imported packages can now be obtained as follows:

import numpy
import watermark.watermark as watermark


watermark(iversions=True, globals_=globals())

---

But I should definitely set up a better documentation some time using Mkdocs that provides examples on using watermark outside Jupyter. I think I never expected watermark to get so many additional features :)
