Support for {git = "https://github.com/gsemet/pipenv-to-requirements.git"}

Hi & thanks for the amazing job on this tool.
I have in my Pipfile some dependencies to Github repositories, e.g. :
polyglot = {git = "https://github.com/aboSamoor/polyglot.git"}
which, if you wondered, comes from a bug in package polyglot on windows (see aboSamoor/polyglot#91 and #22).
(NOTE : this is obtained from running pipenv install git+https://github.com/aboSamoor/polyglot.git#egg=polyglot)

This is currently being translated by pipenv-to-requirements in requirements.txt as:
polyglot
which is kind of incorrect since it simply won't install on my Windows machine when downloaded from PyPi.

Juste came accross #2 (sorry!). Is there a reason this wouldn't work in my case?
Might it be related to editable = True? (i.e. not using pipenv install -e in the first place?)
