Subject: v2.2.4 - Quiet FFmpeg; add "invert" option to Classic Vis; fix CLI
 parsing for Image component (#96)

* change noisiness of terminal output
ffmpeg no longer prints everything into the terminal unless we're in `--verbose` mode. percentage progress text stays on one line while not in verbose mode.

* Added hint to run `avp --verbose` if `avp --log` is run with no avp_debug.log file present

* Classic Visualizer: add invert option

* Image component: fix path commandline option

* Image component: restrict file formats in CLI to match GUI

* Color component: add tooltip to color2 picker (second color of gradients)

* change tests to work with pytest-xdist
avp core stores its config (location of `settings.ini`) in temp directories if using multiple workers to run tests, so they don't interfere with each other. when using a single worker, the `tests/data/config` directory is still used

* check alt comp names when parsing cmdline

* rename `original.py` to `classic.py`

* move `component.py` into subpackage

* rename comp_original to comp_classic

* show traceback if renderFrame() raises exception

* do not try to insert non-existent components from project files

* add "composite" property for components
if a component returns "composite" then it will receive a frame to draw on during calls to previewRender and frameRender

* more tests of projects, actions, waveform, spectrum, image, color, classic

* do not change presetDir to "projects" within PresetManager---
