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...

Trying not to use the term 'GUI' in the Preview menu... show the application's name instead (at the time of the preview click)

Wrong (non-interactive) panels were passed to the INIParser. Not grave because the value
would be empty, but still this was fixed. In fact, start removing IDs
from non-interactive panels. They were given in the beginning so that
specific elements could be targeted, but this was never needed. So now
there's less object IDs flying around. There are probably more that will
be cleaned when stumbled upon, until then they do no harm.

'Alternative' panels. Better error messages.

Now for nodes where we know that the performance saving workaround
makes sense, we can explicitly set it in the attributes. By default,
all children are built. Result: E. g. GEO_HEAT will be filled correctly
even if it's not used because SNP_SOIL is FALSE (without having to state
that it should work in the XML).

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.

simulation. This is work in progress of course, but there's already a lot of information for
the interested user, and it should be more than enough for people knowing
INIshell v1. A few minor tweaks along the way.

Skip over comments before root node, add 'open in editor' context menu for XMLs, show the application's name in the title, shortcuts for 'row' and 'column', add Spacer panel, smaller layout fixes

Add the same mechanism of inclusion/exclusion of sections for <options> (Dropdown, Choice, Grid, ...)

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

Add flexibility to Grid panel (auto-choose row/col, rowspan, colspan, safety checks). Only search for MainWindow once for logging, better XML errors.

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.

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