Extracted base_condition_template, moved from the sale-workflow project
Extracted the description of the module to README.rst
Wrong docstring
Remove 'size=128', there is no reason to limit the char here
Typo in position
Remove a catch-all exception which is useless IMO
Do not hardcode en_US as default language
Big cleaning on the views

* remove deprecated select="1"
* indent 2 spaces
* rename the xmlids
* give better strings and action names
* removed the 'Edit Condition' menu
* Moved the 'Conditions' menu it Invoicing > Configuration >
  Miscellaneous
* added a <group> around fields in form view
* added a search view
* removed the text from the tree view because the html is displayed raw
Added a new module and myself as contributor in README.rst
Added model accesses

The base model only let permissions on the group no_one.
The children modules have to add the rights for the group of their
domains (sale, accounting, ...)
Remove the menu which depends on account

the submodules (invoice_condition_template, sale_condition_template,
purchase_condition_template) will need to add their own menus
Add translations
Set a default value for a mandatory field
