Have split python_(remote_)debugger keybinds

python_debugger (shift+F1) will now always start pdb, and
python_remote_debugger will always start remote_pdb.
Since the new autoreload.py script doesn't break stdin like entr with
live-reload.sh did, we can now use pdb if the app is connected to a
terminal.
