Fix GuideGrid to include rsOtherShowing in the 'will record' highlighting colour. Fixes #12081
Services API: Ignore 'manual' programmes when building the guide. This are psuedo programmes that don't exist in reality but which are created only for the purpose of manual recording schedules. Ideally we'd still display manual schedule periods in the guide, but that's for another day.
Tighten the logic when matching up scheduler data against program showings. This should prevent some invalid data when the exact same program, at the exact same time is covered by two different schedules on different channels.

Fix settings display on macs

Qt widgets uses a default style that varies between platforms. On Linux, the default text is white, on mac its black.
The color of the text in the old settings aren’t configurable as it is (wouldn’t be difficult to do so)

Most themes are using a dark background, so on mac, using the old type settings is proving difficult as mostly unreadable.

So we redefine the style of most QWidget objects so it looks more similar to Linux.
This is done using Qt stylesheets. Where Qt stylesheets do not provided the intended behavior, we use QPalettes instead
MythBrowser: silence a couple of 'no previous declaration for' warnings
Fix AppleRemote thread not being killed when exiting the application

I’ve been seeing the error about the AppleRemote thread still running when quitting for years… had enough
Make python bindings work on mac

We play with the environment variable PYTHONPATH at run time so it points to the current location where the application bundle is located.
It assumes —with-python=python2.6 has been provided to configure (which the mac perl packager will do from now on)
Fix MythVideo general settings page not working

How long that one has been broken ???

The new MythUI screen is always on top, so it must be hidden when starting on old Qt screen…
Hopefully there are no more like this
AlbumArtImages: add some additional debug messages to scanForImages()
MainServer: fix the filename of directory images in HandleMusicFindAlbumArt
MetaIOID3: fix reading of metadata from id3 tags in .mp2 files
Fix old Qt setting screens preventing them from accepting keyboard inputs

Hopefully this is the final fix…
The issue seems to only have occurred on macs. When opening two MythDialogs (that includes MythPopup) in a row, often the 2nd one would not accept any used input anymore, only causing a “beep”; making it impossible to even exit that window.

The existing logic (and there was nothing wrong with it) was to simply disable the current MythDialog and put the new one on top of it. However, when doing so, somehow key events are now ignored.
So instead, we now disable all widgets within that MythDialog, without disabling the dialog itself.

When doing so, the newly created MythDialog is always working as expected.
This code should not be necessary, it is a workaround to what appears to be a Qt bug.

Fixes #11990.
Improve readability of old settings on mac

Text Line background was the same color as the selection. So it was impossible to tell if some text was selected or not. Set background of editable text to a very light blue and keep the text black.
That selection color issue also exists on linux, so we could take the same approach there

Tidy up mythwidgets; and add MythLabel and MythGroupBox.

Fix settings display on macs

My analysis for the problem in 96ecd539de8e76a880f0013b4b8854da216e17b1 was wrong.
The actual issue is that QPalette inheritance appears broken on a mac; if you set the palette to the top widget container, it doesn’t do anything on its children. However, setting the palette to the main application itself does.

Now things look exactly the same between mac and linux for better or worse. Including font sizes and colors.
A downside, is that the selection color appears to be misused in most themes including the default. So you can't tell if a text is selected or simply having focus
