The name was a relict from the very first day of project structuring,
but this name here makes for much much nicer tab-completing to source
file names...

Now we have small icons to make things clearer

... to prepare having "valid" icon

Also switch warning colors

- No need to refresh apps anymore
- change link syntax from help:// to doc://
- add link to help from settings page
- some comments

Now we focus on the styling widget (usually the label), to scroll to the
beginning of the content.
(Otherwise the horizontal scroll bar would center)
Also: use the same color for frame and panel highlighting.

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.

For the styling timer we can not use the static version of singleShot,
because we must be able to stop it (when switching XMLs while something
is being highlighted).
Also, an INIParser object has been leaking

Missing INI keys are now listed more user friendly. If the user cancels
out of saving, the first missing key is jumped to and highlighted in
Inishell.

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).

We use it three times now and getting an environment variable will not
slow it down...

This way widgets that call the styling functions directly will also work
without modifications.

This is neat - if the "primary widget" (the one to style) is a label, an
asterisk is added. If not, the stylesheet is still applied as in
previous versions.

It turns out the most current versions of KDE add keyboard shortcuts to Qt applications. This is the reason for the unwanted shortcuts in the tabs (section names) and in the QCheckBox (multiple choices). See KDE bug https://bugs.kde.org/show_bug.cgi?id=337491. A workaround has been implemented for all Linux and FreeBSD systems (removing '&' in the strings before comparing them or writing them out) but the better solution (besides a newer KDE version) is to add the following to ~/.config/kdeglobals:
[Development]
AutoCheckAccelerators=false

Disable panels' context menus for grouping elements that could show up on a few pixels. Minor XML tweaks and (very) minor code optimization.

Extend the TerminalView's context menu with a 'clear' entry. Add German translation for welcome text

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

Another hotfix for propagating Replicator numbers... now, replace only the first occurrence of '#' so keys like 'TA::FILTER#::ARG#' work

Add description of ZRXP plugin to MeteoIO XML. Add XML shortcut 'h' for 'help', minor styling. Iniqueryparser handles substitutions in keys now. Remove obsolete warning.

With the recent performance fix currently it's not possible to have the same filter listed twice with different parameters showing (because if the wrong one is found first when reading an INI, then the right one's panels are not created)

Fix bug I thought I circumvented when a parent Replicator's number would falsly propagate to child Replicators. Add debug XML node print function.

Don't auto-select items in editable dropdown, give key as tooltip if no help available, minor MeteoIO XML changes

Fix reading order of INI keys (for the moment, FILTER1 = MIN has to be read before ARG1::MIN = ... in order to create the necessary panels. Allow dots in meteo parameters
