BUG: Overwriting existing line

[scottclowe]

• Fix the call to AsLineEditable(), which it turns out is a function in Python (differing from the Echoview documentation)
• Use a try/except block around overwriting lines. If the OverwriteWith method fails, just delete the old line instead!

Closes #325.
