saker aa050ae0b7 Fix memory leaks (#6879)
* Replace knobFModel with std::vector

* Create QPixmap's on the stack

* Assign parent for QGraphicsScene
A call to QGraphicsView::setScene does not make
the view take ownership of the scene.

* Do not allocate QList on the heap

* Use static QPixmap's
The QPixmap's need to be created within the constructor, and not outside
where they are defined, since it can't find them otherwise.
I'm not too sure why.

* Clear m_vi2->knobFModel in destructor

* Use local static QPixmap's

* Do not allocate QPixmap with new in AudioFileProcessor

* Do not allocate QPixmap with new in Nes

* Do not allocate QPixmap with new in Organic

* Do not allocate QPixmap with new in SaControlsDialog

* Do not allocate QPixmap with new in Vestige

* Do not allocate QPixmap with new for FileBrowser

* Do not allocate QPixmap with new in MixerLine

* Do not allocate QPixmap with new in SendButtonIndicator

* Do not allocate QPixmap with new in AutomationClipView

* Do not allocate QPixmap with new in MidiClipView

* Do not allocate QPixmap with new in AutomationEditor

* Do not allocate QPixmap with new in PianoRoll

* Do not allocate QPixmap with new in TimeLineWidget

* Do not allocate QPixmap with new in EnvelopeAndLfoView

* Do not allocate QPixmap with new in PianoView

* Do not allocate QPixmap with new in ComboBox

* Do not allocate QPixmap with new in Fader

* Do not allocate QPixmap with new for LcdWidget

* Do not allocate QPixmap with new for LedCheckbox

* Use m_ as prefix for members

* Use uniform initialization
I already started using uniform initialization for the QPixmap changes
for some reason, so I'm finishing that up.

* Uniform initiaization

* And then he realized he was making copies...

* Do not call QPixmap copy constructor

* Do not call QPixmap copy constructor in SaControlsDialog

* Do not make pixmap's static for Lcd's and Led's

* Initialize pixmaps in-class

* Fix few mistakes and formatting
