requests package still a problem in manual installation

[unsystemizer]

I still have to "do stuff" to install counterparty-cli manually, beginning with requests (similar to before on Ubuntu 14.04, see issue #72).

Currently on Ubuntu 16.04 x64 I have to remove requests and pip, upgrade pip from pip3 and then I can install the right version of requests. After that python-bitcoinlib still has to be installed manually.

sudo apt-get remove python3-requests python3-pip
sudo apt-get install python3-pip
sudo pip3 install --upgrade pip
sudo pip3 install requests=2.10.0
sudo pip3 install python-bitcoinlib==0.5.1 # this will be 0.7.1 on testnet once it's released

Then sudo pip3 install -r requirements.txt finally can work.
Above versions will likely change soon, but at the moment this is what works for me to install manually.
