Stock price Documentation

[Peter Holtermann]

Dear Gnucash users,

based on my python-bindings experience I wrote a short documentation how
to add historic stock quotes to Gnucash using the Intel prices as an
example: http://wiki.gnucash.org/wiki/Using_GnuCash#Stocks

Please have a look and give me feedback if you understand what I did (or
not :), if something is missing and so on.

All the best,
Peter
