This data can still be overwritten from within the Plugin itself by setting the correponding __plugin_xyz__ variables, however it allows getting rid of some repetition if that data has already been specified in setup.py
In order to solve the initial handshake problem with apps, OctoPrint now supports so called app session keys which are basically API keys with a limited validity. Obtaining those keys is based on a handshake procedure backed by RSA signatures. OctoPrint needs to be aware of apps and their associated public keys (with the AppPlugin there exists a mechanism to add additional recognized apps by installing a plugin). Apps perform the handshake by first requesting a temporary key with very limited validity, then sending a message back to OctoPrint containing their id, version, the temporary key and a signature created with their private key over these three pieces of data. OctoPrint then tries to verify the signature and if successful unlocks the key to be used as a fully recognized API key.
Also included is a translation for (informal) german.
New languages can be added with "python setup.py babel_new --locale=<language code>" which will create the corresponding .po file from the existing .pot file under "src/octoprint/translations/<language code>". Translations can be refreshed from strings in source with "python setup.py babel_refresh". Existing translations can be compiled into usable translation files (.mo for python and .js for Javascript) via "python setup.py babel_compile".
You'll need to install the development dependencies for all of this to work, just issue "pip install -r requirements-dev.txt"
Note: numbers are not yet correctly formatted for their respective locale (e.g. "2.5mm" instead of "2,5mm" in german).
4.0.1 is currently causing issues with OctoPrint, this is a quick fix for that until I have the opportunity to investigate this further.
Workaround for second issue in #544
Allows reading and writing default serial port and baudrate (this also is available via the web interface) and setting the host and port on which the server should listen. Might allow persisting more options in the future.
The configuration file is stored in ~/.printerwebui/config.ini under Linux, in %APPDATA%/PrinterWebUI/config.ini under Windows and should be stored in ~/Library/Application Support/config.ini under MacOS X
