- As of v10, manifest files should be named `__manifest__.py`
- For backwards-compatibility, __openerp__.py manifest files
will still be supported for the time being
- Limited refactoring, to add support for the 2 different
naming conventions
- All textual references to __openerp_.py updated in
documentation and examples
Manifest files are literal Python dictionaries, and
aren't supposed to contain expressions that require
a full-fledged eval.
`literal_eval` is therefore sufficient *and* safer.
This parsing method was already used when listing addons
during startup of the Root controller (http.py, load_addons())
