For some reaons with recent versions of Qt we can't embed the VST FX
GUI into an existing EffectControlDialog anymore. As a workaround, embed
it into a new subwindow and added an additional show/hide button.
Closes#3028717.
(cherry picked from commit fa9e0f762c)
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
