[9.0E] Flanker not found, missing Python library in requirements

[Yenthe666]

Impacted versions: 9.0 Enterprise

Steps to reproduce: Install a new Odoo V9 Enterprise and install the module website_crm_score.
Check the logfile afterwards:
2016-04-30 11:06:53,802 2605 WARNING ? openerp.addons.website_crm_score.models.sales_team: flanker not found, email validation disabled.

Current behavior:
Warnings in the Odoo logfile when Flanker is not installed

Expected behavior:
Flanker should be either added as a requirement on requirements.txt or it should be automatically installed on the system when you install the module website_crm_score?
Either way, there is no way for the system administrator to know that this Python package should be installed and it is not mentioned anywhere.

@mart-e I think you might know this. Is it by purpose not in the requirements.txt since it is only used in enterprise or?

This is not an mandatory dependency, the module will still work without this, just the verification of email addresses that will not be present.
We have a few of those, as it is very specific (webiste_crm_score is quite advanced, requires complex configuration), we don't want to impose it to everyone.

So no, I don't think it should go in requirement.
We could add information about this in the description of the module though.

Alright so it does make sense that it is not a requirement but, honestly, without opening the logfiles you would never know you'd need it.
I think it would be a good idea to add it in the description of the module and also on the documentation later on.
Perhaps a little warning could be thrown up in Odoo too? On the moment you install the module or something. Just a simple dialog.

PR welcome 😉
I am not fan of popup warning (because people seeing the popup are probably not necessary the people that can do something about the problem) but sure, we can put it in the description of the module.
