[FIX] packaging: add BeautifulSoup to py2exe setup

When trying to import an OFX bank statetement under MS Windows, a
Traceback states that BeautifulSoup is missing.

During the build process, py2exe didn't autodiscover that BeautifulSoup
is needed by the ofxparse package.
With this commit, BeautifulSoup is explicitely added to py2exe packages.
The Nightly VM was updated accordingly.
