[ADD] odoo-bin cloc cli subcommand.

Odoo cloc is a tool to count the number of relevant lines written in Python,
Javascript or XML. This can be used as rough metric for pricing maintenance of
customizations.

It has two modes of operation, either by providing a path:

    odoo-bin cloc -p module_path

Or by providing the name of a database:

    odoo-bin cloc --addons-path=dirs -d database

In the latter mode, only the custom code is accounted for.
Both modes can be used simultaneously.

Files that cannot be parsed are shown at the end of the report.
Parsing can fail due to syntax errors or excessive file size.
