Release 0.2.2: using shells

Added

• Added a command to manually query module info (gr_modtool info):
  a workaround to activate the extension when the module has no blocks yet
• Added actions to compile/run GRC Flowgraph files or edit them in GNURadio Companion from the editor titlebar
• Added a filter (regex) when creating Python bindings, making YAML from implementation, disabling or removing blocks
• Added automatic blockname for modtool commands when a corresponding editor is in focus
• Added an option to pick Python/C++ QA when creating blocks

Changed

• For modtool commands: replaced child_process with python-shell + wrapper scripts
• For gnuradio-companion and grcc: replaced child_process with terminal (shell) tasks

Fixed

• Fixed validation warning preventing the use of short names when creating blocks
• Fixed sanity checks when creating Python bindings or converting XML to YAML from the context menu
• Fixed GRC Flowgraph commands not executing on currently open files
• Fixed YAML block filter not working because of mismatched extension (.yml vs .block.yml)

Removed

• Removed GNURadio modtool command from extension settings
