F1 brings up keys help in curtsies
don't hardcode pager
talking to a subprocess
using watchdog to reload
add time of last reload
Verify if a module actually has a __file__ attribute so watchdog can watch it.
less unnecessary reloading
use events instead of hardcoded keypress
prevent permenent message from reappearing after message
Temp status bar things messages clear automatically

requires master curtsies
TODO use a different event type - this kind of scheduled refresh
is really different than "I need a refresh so I can keep doing
my thing"
Toggle file watching on and off with F5

Currently only turns off reloading, NOT WATCHING OF FILES!
Move reloading code into curtsies Repl object
dealt with cases involving rewinding and toggling watching
