Immediate that is in the preview "Editor" widget in the Profile Preference
(settings/option) dialog - changes to the main Editor (for all and each
profile) are not made until the dialog is closed with a save but as the
Editor built into one tab is supposed to be a preview it needs to change
as the options are.

Note that currently showLineFeeds/Paragraphs is not like the original
Qt Text Editor widget - instead it just puts a graphical line between each
line of text.  I believe it is possible to revise this upstream in the
Edbee-lib repository to be more like the LineEnd/Paragraph markings of the
original Qt widget but that will take a bit of time to do that I do not
have right now.

Also note that changing the show tabs / spaces option did not take effect
immediately in the Edbee editor widget but I have put forward a bugfix for
that which has already been accepted into upstream as:
PR edbee/edbee-lib#33 as a fix for:
issue edbee/edbee-lib#32

* Revise: ensure all aspects of edbee settings persist on item change

During testing I found that previous changes to the edbee widget set in the
profile preferences did not stay when a new Mudlet item was selected in the
editor and that a theme setting made in that dialog was routed to ALL
profiles instead of the active one.

The first of these issues I solved by ensuring all of the Font, the Theme
and the two global settings for show tabs/spaces and (the currently
misused) linefeed/paragraph marks are all set when
dlgTriggerEditor::clearDocument(...) was called.

The second was fixed by removing the inappropriate
(void) mudlet::setEditorTheme(const QString&) method and the SIGNAL
signal_editorThemeChanged(QString); the latter was wired up to a lambda
method in the dlgTriggerEditor constructor, what it did was needed but only
as a method called by (void) dlgProfilePreferences::slot_save_and_exit()
which was named
(void) dlgTriggerEditor::setThemeAndOtherSettings(const QString &).
