v2.2.1 - fix #74, fix #92, add optional 64th bar to Classic Visualizer, improve Conway default (#93)

* update gitignore
ignore profiling and coverage data

* F1 opens help window, create appName variable, move undostack class

* fix kaleidoscope effect, increase default Y values by +4
the increased y values allow the cells to continue animating for more than 60 minutes instead of 30 (at default 60f/t)

* update version number

* add minimumWidth to undo history window

* Classic Visualizer: option to include 64th bar

* Waveform component: fix #74 - new animation speed option

* move shared visualizer code into toolkit

* Waveform component: compress audio by default

* Waveform component: fix 100% animation speed

* new components receive random color

* update to Qt 6

* fix pushbutton stylesheet

* fix #92: replace ok/cancel with save/discard/cancel

* remove obsolete PaintColor subclass

* mv common shadow code into addShadow func

* add 3rd option of ok/cancel back to showMessage
the 3 options are:
- ok
- ok/cancel
- save/discard/cancel

* Image component: add shadow option

* small test of rgbFromString

* fix color tuple string

* test another way to get comp names from CLI

* rename component tests, add some more

* Image component: scale shadow based on resolution

* catch AttributeError if previewRender returns None

* Text component: fix blur radius only able to increase
the relativeWidgets system causes QDoubleSpinbox to only allow increases, because it really only works with integeres, so I changed the blur radius into a normal QSpinBox. I noted where the problem exists within component.py for future reference. This commit also removes an unneeded VerticalLayout from the ui file

* remove unnecessary QVBoxLayout

* paste shadow at x,y instead of using offset method

* fix tests due to shadow change

* don't print warning in connectWidget due to QFontComboBox
