Add support of mongoengine module.

[goldan]

Prevent 'no-member' errors for Document._meta, objects, id/pk, save and errors.

thanks for this, it's exactly what I needed!

mongoengine is not specific to Django though, this belongs in its own plugin rather than here IMHO

[anentropic]

suggested change: objects = type (instead of None)

code like this is valid in mongoengine:
uk_users = User.objects(country='uk')

without the change above pylint complains that "objects is not callable"

Agreed that this good thing doesn't belong in a Django plugin.

[goldan]

Agreed, though I don't feel like creating a new plugin for 15 lines of code... that's why I posted it here.

Awesome stuff! Sorry for delay!
