[8.0] account_move_batch_validate: ImportError: No module named connector

[moylop260]

My project use this one and today I had next error:

  File "./odoo-8.0/openerp/http.py", line 1308, in load_addons
    m = __import__('openerp.addons.' + module)
  File "./odoo-8.0/openerp/modules/module.py", line 80, in load_module
    mod = imp.load_module('openerp.addons.' + module_part, f, path, descr)
  File "/home/travis/account-financial-tools/account_move_batch_validate/__init__.py", line 23, in <module>
    from . import account  # noqa
  File "/home/travis/account-financial-tools/account_move_batch_validate/account.py", line 28, in <module>
    from openerp.addons.connector.queue.job import job
  File "./odoo-8.0/openerp/modules/module.py", line 79, in load_module
    f, path, descr = imp.find_module(module_part, ad_paths)
ImportError: No module named connector

This is by next issue:
odoo/odoo#7507

This needs to add a try-except ImportError: log.debug sentence similar to CONTRIBUTING.md#importerror to don't force my project to use other one that we don't use.

For now I've suggested this PR #279, the problem comes with the static folder and icon add.
