[ADD] standard files

I guess the concern is that it makes sense to run all tests in case some addon 
breaks core functionality (poorly done monkey patches, fuckups in BaseModel 
etc). That's a valid point I think, but that should not be covered by every 
single commit test.

The good approach for this would be an OCA-wide test run so that we can be 
sure that all OCA modules play nice with each other and with (possibly OCB) 
core. Something like an OCA-runbot.
