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).

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

codemirror: display an animation in window title so that the window flash when component has been saved.

Use case: save component on one tab, go to "run live test" tab and wait for component to be saved to make sure code runs with latest version

This is probably incorrect. I believe ERP5ShortMessage's message_type
handling has to be refactored. I guess this should not be part of the
send API but be a property set on the gateway instance in portal_sms

Only mobyt support this parameter, so this break the compatibility with
essendex

this way after a zelenium tests ERP5Site_setupDummyMailHost this will
also reset the mails that could have been sent in previous tests.

This sends too many emails.

Some parts were outdated

The main purpose of these changes is to activate call to portal_sms.send; This way it is isolated it in a transaction that is less likely to fail. Activate with max_retry=0 and conflict_retry=False not to send activity twice in case of error.

There are other cleanups, see individuals commits.

Since sending email will not work without destination email, we can globally set this constaint

This way it is isolated it in a transaction that is less likely to fail. Activate with max_retry=0 and conflict_retry=False not to send activity twice in case of error.
As with email, if there was an error in activity processing, it is advised to investigate the transport logs to see if message was send or not.

event_simulation_workflow already call `send` type based method upon start transitions.
This workflow was not chained to portal_type, but if it would have been then message would be sent twice.

It allows to not cancel the loading of the iframe and to prepare the appcache.
The former behavior removed the iframe thus interrupting the preparation of
the appcache.

re-apply 25cd1201 that was mistakenly reverted by b847b45e

Hey @Nicolas can you please take a look at all this ?

All this started when I realised we probably do not want to allow grouping reference to be set when we have transactions from different ledgers ( edda8b58 ) and then realized it would be required to allow choosing ledger in grouping fast input instead of just showing all ledgers together ( d1ecbe29 ).

The rest are small changes to move out complex logic from TALES to a script and small fixups.

Thanks
