[PATCH 2/5] RecipeParser: add support for PyRecipes

[Jiri Prochazka]

For PyRecipe network definition, the syntax is the same as it was
for Python tasks, eg. when network is defined in file network.py,
network tag in XML recipe will look like this:
<network python="network.py" />

RecipeParser will check if network is defined with python attribute,
and returns path to the file in recipe["network"] variable.
