ipython_view: Add keyboard shortcuts to clear input after cursor (Ctrl+K) and copy selection (Ctrl+<uppercase>C)
requested to merge michaelweghorn/accerciser:michaelweghorn/ipython_add_more_keyboard_shortcuts into master
This adds two more keyboard shortcuts for Accerciser's IPython console that are also available when using a standalone IPython console in common terminal emulators:
- Ctr+K to clear the input after the current cursor position
- Ctrl+C (only upper-case C) to copy the current selection
