This is the first step of the transition to a "slightly" changed
externals handling. As explained in [1] and [2] "patch.exe" is needed
for the win users - linux OS do usualy already include "patch".

The download SHOULD not take place without explicit question to the
user. This was a bug and was solved in [3], please update if needed.

The reason for all this is, that we use external code from other
projects/sources, as e.g. "BeautifulSoup.py", but also others. Most of
them used by 2 of my bots (subster.py and catimages.py). What I
implemented is an automatic check and install system for missing
dependencies in externals/__init__.py. This system is able to install
exactly the version requested by us the developers and allows to apply
patches to the code if needed - in order to have maximal flexibility.
It can make use of the linux OS package management or directly
download the code from a defined location. More up to come.

The question whether this is the best solution possible should be
discussed. As I see it yes, because we do not need to fork all those
projects and then maintain (update and merge) all the code all the time.
I consider this as sub-optimal because of the additional workload
produced. But if somebody has a good idea or can explain me how to do
this properly, please step forward! I am NOT an expert, especially in
git and there might be better solutions.

At the current stage just downloading of "patch.exe" for win users is
activated. The next step from my side - if everybody agrees - would be
to activate this system for BeautifulSoup.py for further testing. This
would mean that BeautifulSoup.py would be removed from our repo and in
future be automatically downloaded (after a question to the user) at
the first run.

Greetings and I looking forward to all your feedback
