[review] Installation process

[fdroessler]

I would suggest not to be explicit about where on the system a user should install qtools. I think just changing the README so that the instructions are a bit more general could avoid confusion and some other issues. Something like this maybe? Or alternatively using setuptools/pypi.

README content:
...
Clone the repository to your local directory:

mkdir -p <path_to_installation_folder> && cd <path_to_installation_folder>
git clone https://github.com/mpurg/qtools

Add this line to your ~/.bashrc or ~/.bash_profile:

source <path_to_installation_folder>/qtools/qtools_init.sh

...

Also this line can cause issues if PATH contains hardlinks:

qtools/qscripts-cli/qscripts_config.py

Line 121 in baf501d

for ex in os.listdir(path):
