Wiki copy action doesn't copy images

When the wiki is updated after a merge on "master", only "*.md" files are copied to the Wiki, images are not included.

Images should be included as well.

Add button debouncing and event queue

Add support for samplerates other than 44.1kHz

Add User Manual to the wiki

Add more comments and code documentation

The new C++ based firmware could use better comments and doxygen documentation.

"Internal error" during playback

While playing music, sometimes an "internal error" is triggered so that the status LED shows the "internal error" pattern. It seems related to #1 as it typically occurs at the transition from one file to another. Probably caused by incorrect handling of mp3 decoder return codes.

Use hardware watchdog to reset after software crash

Detect card removed during playback

When the card is removed during playback: Display error code, turn the box off

Playback skips portion at the end of each file

Add release binaries

Add build videos

Add build videos on YouTube.

Add CI checks

e.g. Travis CI - use settings from Electrosmith Daisy - libdaisy.

Play sound when error occurs

Sounds could even be spoken words. There should be enough space in the flash memory

Add "skip forward/backward" when holding the buttons

This could be done by registering a long press on a button.
Pressing and holding a button will then add "ui_event_XYZ_held" events to the event queue. These events could be used to skip MP3 frames

Add Build Manual to the wiki

Add "pause" and "resume"

Enter pause when pressing both buttons at the same time.
Resume when pressing any button while paused.

Add clang format file

and add checks to the CI - see #9

Automatically split bottom/top boards before gerber export

Currently the gerber files include both the top and bottom boards in one single set of gerber files. This is not supported by most PCB fabs. Using python scripting we could try to remove components and traces from the Kicad pcb files prior to the export like this:

import pcbnew

def isAllowed(position):
    return position.y > 160

pcb = pcbnew.LoadBoard("Wunderkiste.kicad_pcb")

for module in pcb.GetModules():
    ref = module.GetReference()
    print("- Module: " + ref)
    p = module.GetPosition()
    if not isAllowed(p):
        pcb.Delete(module)

pcb.Save("Wunderkiste_topOnly.kicad_pcb")
