Use translated names of barlines in timeline.
Change to use SMuFL names for barlines so we use the same strings and
translations in basic and advanced workspace palettes, master symbols
palette (untranslated before), inspector and timeline.
Previous versions won't show them and also loose them on save
* fix 383 warnings C4996 (deprecated) with one single line change
* fix 5 'empty' warnings about invalid slots, not sure the remaining
slots serve any purpose though
* disable warnings C4127 and C4996 for thirdparty/google_analytics
* fix 30 warnings C4996 using the suggested alternatives available since
at least Qt 5.9, so won't break building against that
* change as requested in code review plus some more fixes using the same
idea
* fixing yet more warnings
* disable deprecation warnings in qoogle_analytics for MinGW too
although I believe maxOS and Linux may use those too. Easy to extend to
those, if need be.
* Fix qml runtime warnings exactly following the advice given by that
warning, but without really know what I'm doing here or whether that is
still backwards compatible to Qt 5.9.
* Use replacements as suggested, if available and no `endl` neded with
`qDebug()`
* fix 24 more
* 2 more
* 7 more (one only seen in DEBUG mode)
* Fix the `endl` warnings
* maybe more changes this way?
* Add all warnings C5999 or bigger to the ignore list for telemetry
with Qt 5.15 Beta 1 as avoiding only C26439, C26444,C 26452, C26495,
C26498, C26812 isn't possible
* fix 2 deprecation warning new with Qt 5.15 beta 1
* fix 4 new warnings and also Qt 5.12 builds, disable some dead code
* fix deprecation warnings new with Qt 5.15's MSVC 2019 integration and
revert some (`QNetworkReply::networkError()`) that Qt 5.15 beta 2
reverted too
* fix warning reg. obsolete operator < for QVariants
* revert changes needed prior to beta 3 And clarifying some earlier
changes
* mark ToDos
* fix warning reg QString()::null
* fix a 'regression' from a revert of an earlier change
