There were still crashes where a Timer was called on an invalidated
object. Now, this timer is in Atomic and therefore gets destroyed with
the widget.
This way we can have multiple stylings running and it is more logical,
cleaner, and more general purpose.

It can still either be a frame (border is flashed) but now also any kind
of input panel with it's respective key (it is highlighted for a short
period of time).

Files opened from the filesystem are now read only and not marked as
"modified". A tooltip listing the major shortcuts has been added. The
regex for coordinates has been improved (it is now the same as at the
other places in Inishell).

Otherwise, re-ordering of the variables declaration for better
alignment.

Because there was no way to completely reset a Numbers panel (there can't not be a number in a spin box) this is now possible via a generic context menu in all panels. Restructure the menu a little to make these functions more clear

re-check on onPropertySet when the value does not actually change.

Some comments.

Formerly INI keys were changed live when changing the value through a
panel, eliminating the need to loop through the panels for output.
However, this introduced more and more intermediate loops (like
disabling child panels of Dropdown, Choice, ... that are not shown) and
gave some headaches when working with missing mandatory values and
similar things. Hence, now we keep the original INI values read from
file as they are and and do loop through the elements at the end to get
the user set values.
Also add a few toolbar buttons and minor changes here and there.

Some comments

Manage suppression of ouput that is not active (e. g. not selected in a dropdown), and start a mockup Workflow element

Selector and Replicator can act on values given in INI files.
