Update installation guidance for Windows.

[mpl...@gmail.com]

Guys hi,

Now the installation guidance suggest to use Cygwin or "Windows Subsystem for Linux" for Windows.

Cygwin was working fine with beancount, but when i tried to install smart importers on Cygwin it was hell.

Smart importers depend on scipy and installing it on Cygwin is very problematic

"git clone https://github.com/beancount/smart_importer.git
pip install --editable smart_importer"

on Cygwin does not work, gives lots of errors, etc.

after trying different ways i finally made it work using this

https://www.codefull.org/2015/12/installing-scipy-numpy-and-matplotlib-under-cygwin/

still it was very painful :)

But you don't really need cygwin now to run python on windows. Installing python/beancount directly on Windows was very easy in comparison.

What i did:

1 installed python from https://www.python.org/ (this video is helpful https://www.youtube.com/watch?v=gFNApsyhpKk)

(this installs pip, lxml, etc)

2 pip install python-libmagic

pip install python-magic-bin

(without them beancount ingest was giving error.

"$ bean-check" was passing the installation test, but beancount ingest was giving error)

3 pip install beancount

4 git clone https://github.com/beancount/smart_importer.git
pip install --editable smart_importer

that's it, no need for https://www.codefull.org/2015/12/installing-scipy-numpy-and-matplotlib-under-cygwin/

I know not all beancount users will use smart_importer, but at least it will be easy for them to do if they will want to try it.

(p.s. i am using Windows 10, it might be different for Windows 7, but i believe Windows 10 is by far most widely used Windows version now)

Also when researching options to make scipy work on Cygwin/Windows i've met lots of recommendations to abandon Cygwin for Anaconda, but did not try it so can't comment on it.
