Converted doxygen style comments to reStructuredText style in the files
found in Cura/cura/Model directory recursively using the script
dox_2_rst.py (provided in the Uranium repo). Comments were manually
checked and changed if needed.
Note: dox_2rst.py struggles with decorated functions.
Removed the dependency of the DiscoveredCloudPrintersModel on CloudOutputDevice,
which is Ultimaker specific. This can allow even external plugins to add to this
model in the future.
