No need to use a opaque user id. If we use mail address, to enable
google login for an existing user, we just have to "create google login
with email address and validate google login".

A more apporpriate place would be a dedicated "signup using oauth"
page, relying on erp5_credential for the actual user creation.

ERP5ExternalOauth2ExtractionPlugin: document a bit how this plugin and ERP5LoginUserManager interact

Merge remote-tracking branch 'gabriel/support_google_login' into master_calendar_wip_patches_extend_security

erp5_oauth_google_login: Zope user should not see this action because to create a Google login is required that a person in ERP5 exists

We are expecting user_id instead of username

erp5_oauth_google_login: s/erp5_username/user_id/g to be with consistent with Base_getUserValueByUserId

ERP5ExternalOauth2ExtractionPlugin: Fix query to find logins properly. It should be squashed in 4089f516

login_form: Use ERP5Site_getAvailableOAuthLoginList to know if google login is supported or not. With this, we can extend to other oauth easily

erp5_credential: Add link to login in ERP5 with Google Account and use zocial.min.css to display it nicely

erp5_xhtml_style: Add link to login in ERP5 with Google Account and use zocial.min.css to display it nicely

Add margin-top to display zocial buttons not too close from other buttons or links

Google Login follow the same implementation of ERP5 Login(subobject of Person) and with an action in preferences, the user can add Google Login to his person.

instead of implementing this logic in ZSQL's DTML

Revert "erp5_calendar: Update stop_date, otherwise it can stay in the past and generate wrong duration (stop_date - start_date)"

This reverts commit 6af8eca1f4d7fbdd29cd001b1c5a7d4d03b51990.

SimulationTool_zGetInterpolationMethod is called in restricted context
of Resource_zGetMovementHistoryList so it needs to be usable by
anonymous.

ZSQL Method does not read parameters from REQUEST, so it looks safe.

We should be able to configure a group calendar saying that the pattern
is "from 9:00 to 12:00, repeat every monday morning" with a group
calendar assignment saying "use this pattern from 01/01/2016 until
31/12/2016" and then create another group calendar assignment for 2017
without having to change the periodicity stop date on all presence
periods of the group calendar.

I think it should repeat from group calendar assignment's start date
until min(group calendar assignment's stop date, presence period's
periodicity stop date).

(cherry picked from commit b42a9c11)

 - update PresencePeriod.getNextPeriodicalDate with fixes from 6155f7ff
 - do not use addToDate, but simply DateTime arithmetics that unlike addToDate, works correctly

(cherry picked from commit 30e2c1f6cb55ae3dfc4d8c83911b53f38a6cc36d)
