Hydrogen 2.0 (H2O)

⚠️ Breaking Changes

Support multiple independent kernels #1008, #40

Three commands to start a new kernel:

• "Start Local Kernel" (default when executing code in a new file)
• "Connect to Existing Kernel" (replaces "Switch Kernel")
• "Connect to Remote Kernel"

Main Changes:

• Kernels are indexed by file path
• By default a new ZMQ kernel is started when users runs code in a new file
• Users can connect multiple files to the same kernel via "Connect to Existing Kernel". This also supports remote kernels
• "Switch Kernel" command is removed since it's now obsolete
• "Select Kernel" command is renamed to "Start Local Kernel"
• New "Kernel Monitor" panel to manage all running kernels (open with "Toggle Kernel Monitor") :
  

Don't rely on jupyter to discover kernel specs #1031, #1039, #1046

This removes jupyter as a dependency and will significantly decrease startup time.

Main Changes:

• Remove Kernelspec setting. This setting was introduced because we ran into some issues where jupyter was not available from Atom. Editing this setting is a horrible user experience and everything can be achived by properly installing the kernels too.
• Remove support for old python installations, relying on deprecated ipython kernel directories.
• The default Python installation won't be discovered anymore. The IPython kernel needs to be installed with:

  python -m pip install ipykernel
  python -m ipykernel install --user

🎉 Features

• Make text in panes (inspector, output, watch) copyable #1017, #1029
• Add setting to view output in dock by default #1022, #995
