add requirements.txt for pip install

Is your feature request related to a problem? Please describe.
Not exactly related to a problem but a requirements.txt file will allow contributors to easily install dependencies with pip install -r requirements.txt

Describe the solution you'd like
I added a requirements.txt file here in my branch containing external packages used. I will like to create a pull request from this branch

Describe alternatives you've considered

• Based on this issue and from experience, it is a bit difficult to install plyvel on windows. A leveldb prebuilt version for windows can be found here.

Note
My branch makes changes to .gitignore file. pycache/block.cpython-36.pyc, pycache/blockchain.cpython-36.pyc, pycache/pow.cpython-36.pyc and other *.pyc files will be ignored if pycache folder is ignored.

Contribution Guide

Since you have chosen to use leveldb, I intent to use a pre-compiled one found here. It is quite easy to use. I will like to hear your feedback before creating a pull request for part_3.

Tasks to do

• part3: LevelDB is using lexicographical only to handle data, so blocks will not be ordered in insertion. Use 'b{height}' prefix to identify block's data.

• part4

• part5

• part6

• part7
