Ref #205 Update to interfaces related to recurring events, as well as a number of bugfixes. The sql for a required table, `global_lu_restricted_days` is in the 1600 upgrade entrada.sql file, but I've just added it into the install sql now, so make sure you have that if using recurring events.

Ref #205 Fixed issues that Ryan Warner identified. Recurring events should now start the day after the original event, and end at the end of the day set as the end, rather than before it.

Ref #205 Changed events in the modal dialog for selecting which recurring events to apply changes to, so that the name/date of the event is now a label for the checkbox.
Refs #435, fixes community_notify's permissions query for "post" content types.
Refs #360, allows enrollment in curriculum periods that have already passed.

This just takes off the `finish_date` >= NOW() restriction when selecting a curriculum period.
Refs #303, fixes success message for activating learners in Manage Cohorts.

When activating/deactivating/deleting learners from a group, the repeated message "Successfully activated the selected group member" is replaced by "Successfully activated <name of learner>".

On the Edit Groups interface, the "Delete/Activate" button has been replaced by a green "Activate" button and a red "Delete/Deactivate" button. When the user clicks on one of these it passes their choice via POST (not GET since the form is already submitting via POST) so that on the confirmation page there is either a green "Activate" button or a pair of "Deactivate" and "Delete" buttons, but not both.
Fixes bug whereby Quiz response feedback was being saved regardless of whether the feedback checkbox was checked or not. Refs #362
Fixing the version_db setting in the database install to be up-to-date with the versions included, as a few had been missed which were in the upgrades.
