Refactored running loop().

- shouldExitLoop() is a bool again and introduced new flag isReloaded() instead
  of adding special hacky value 2
- loop() accepts 2 parameters: loop substatus and shouldExit flag, because each
  caller previously had to set and restore these manually.  loop() now also
  tests whether the substatuses are properly nested.  reordered the
  loop-exitting code.
- renamed loop substatuses to logical names
- enterNewRoom() returns bool whether loop() should continue so that start()
  doesn't have to test and clear shouldEndProgram().  it doesn't need
  force_reload as a parameter anymore.
- dialog selections use new inner substatus instead of outer substatus, for
  consistency
