🚩PR: Added feature of GridLayout repositioning

[elsoazemelet]

Closes #445

• Now when holding down the control key and click + dragging with the mouse, the displayed modules can be repositioned
• This repositioning is resets when clicking the Reset Grid Layout button on the Tracker
• Check the tooltip for this feature next to the reset button
• When the sticky container (that contains the page changer buttons) is would be outside of the middle panel, then it automatically sticks to the bottom of the screen
• When no module is connected the positioning is reseted to the center
• This feature is not persistent, the restart of the editor should reset the positioning.

Reset Grid Layout is not a very descriptive name for the button that resets the position of the whole layout. Preferably is should somehow tell the user about that.

This button received the same highlight colors that all other buttons use now, like the Discard button. I still feel like that their highlighting is way too unnoticeable. Dark button in front of a dark background becoming slightly less dark is not a great way to highlight.

For some reason the tooltip disappears after clicking on the tooltip questionmark. This issue affects all tooltips, made a separate issue about this here: #629.

All other features work as described.
