Fix VHostScan installation issues

[ibitebyt3s]

People seem to be struggling to install VHostScan as in issues #122 and #123 and I found that by removing the version numbers in requirements.txt The install and test scripts would run flawlessly.

I also updated test-requirements.txt to follow the same "version numbering" in both *.txt files.

Lastly, I removed pytest command example from the README.md because it uses python2 which is now deprecated. The problem with it is that it was trying to import the ipaddress module and since pip2 is not available, it would be problem to install it and keep building on top of it.

In conclusion the following commands should run without issues:

sudo python3 setup.py install
sudo python3 setup.py test

I had the same issues installing but your fork seems to work, thank you.

Edit: Installed fine but running VHostScan.py gives the following error:

You might be calling the script with:

python3 VHostScan/VHostScan.py                                  

instead, call it as any binary in the $PATH variable. Just type VHostScan and you should get the proper banner and usage information. Let me know if you have other issues.

latest requests (2.26) breaks the code, using requests==2.20.0 works like a charm.

for the records, i had it working doing:

apt-get install subversion python3-venv
ln -s /usr/include/locale.h /usr/include/xlocale.h
fix requirements.txt

python3 -m venv .venv
. .venv/bin/activate
pip install wheel
pip install numpy
pip install requests==2.20.0
python3 setup.py install
