Document an example wait timeout for MySQL in case the web hoster is killing the connection too early - fixes #15407

Signed-off-by: Stefan Weil <sw@weilnetz.de>

Add unit testing capabilities for templates

Composer 1.1 has since yesterday a new performance improvement that will be automatically used for PHP >= 5.6, however this file is incompatible with older PHP versions and thus we need to exclude it from the checks.

Note that this performance improvement is only used on >= 5.6 so ownCloud will still run fine on older PHP versions as well.

* remove ie8 fixes for checkboxes

* add indeterminate style to checkboxes

* add styles for radio inputs

* add missing checkbox-mixed-disabled icon

* fix white radios

* remove unnecessary png file

The hook now calls the share manager that will call the responsible
shareProvider to do the proper cleanup.

* Unit tests added

Again nothing should change it is just to cleanup old code

There is no need to calculate the permissions twice.
Saves some is_dir and file_exists calls.

Remove pre/post_addToGroup hooks for shares

* same as #18839 for legacy jobs
* avoids spamming the log with useless entries

* To be safe don't unload until end

* unlink needs to be before return to actually do anything

re-try to send unshare notification if remote server is not available
