Finished parameterizing features/steps/scenario_account_stock_anglo_saxon.py
    You should be able to use this feature to build productions systems.

    Made a first attempt at porting DSL from OpenERPScenario.
    Not documenented or tested yet.

    Now switching to Tryton 3.0 for development from now on.
Added features/steps/oerpscenario.py
which are the elementary tests from OpenERPScenario.
The aim here is to make the same feature tests in OpenERPScenario
run in trytond_scenari on Tryton. YMMV!

Refactored the scenarios to use a Set of default feature data.
This will allow us to un-hardwire the account names, and run the
same testing scenarios on Chart of Accounts other than the
default "Minimal Chart of Accounts" in the account module.

Made features/steps/support/fields.py use tryton to get field
data types. Anything that is not a basic data type is assumed
to be the "name" field of a relation, and the OerpScenario
syntax of 'by name: Name' is dropped to just 'Name'.

I'm not sure if we want to support the OerpScenario syntaxes of
'by oid:' or 'by code:' - if so, fix features/steps/dsl.py
which is currently broken, and keep the syntax local to those steps.
