Improve install_requires and setup_requires

[GokulNC]

I did a pip install ., but I get the following error when transliterating:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Program Files (x86)\\Python37-32\\lib\\site-packages\\libindic\\transliteration\\cmudict.0.7a_SPHINX_40'

Please fix the issue with the given solution to include all non-code files.

f5653c1 dropped MANIFEST.in in favour of setuptools-git

I dropped the setuptools-git dependency in b751902 without knowing this. My bad.

Let me fix that.

Thanks @asdofindia

Is it possible to add install_requires in the setup.py to include setuptools and also other dependencies from requirements.txt ?

[asdofindia]

I'm unsure about that.

Cons:

• Duplicating the list of dependencies risks these going out of sync

Pros:

• Easy installation?

This answer says we can put a . in requirements.txt and use install_requires to actually list down dependencies.

I think I'll try that. @santhoshtr @copyninja
