'CTRL + S' in "Edit Task" view opens "Save file" dialog

[dantefromhell]

Issue

When creating or editing a Task, using the "CTRL + S" keyboard shortcut opens the browsers "Save File" dialog.
Except when the text cursor is in the Description field, than the keyboard combination triggers the "Save" button on the "Edit task" form.

Proposed solution

CTRL + S seems to be a common shortcut in HumHub to save information/ changes.
Hitting the keyboard combo while the 'Edit task' dialog is open should always trigger the dialogs "Save" button - independent of the text cursor.

Tested version

This behaviour was verified on a hosted HumHub demo running
