FMSLogo Code

Fix a shutdown crash when the screen was occulded and the workspace was dirty.
In this case a screen re-paint message could come in after the main frame had been closed.
The fix is to simply ignore the re-paint message in this case.

This was a regression from FMSlogo 7.7.0. I don't know what caused it, but it might be that updating wxWidgets changed something subtle in the way it handles messages.

Fix a typo in a comment.

Fix Bug #551; Esscaped newline characters now SAVE as "\n"
Before, it saved as a backslash followed by a literal newline character.
This provides symmetry with the the logic that George Mills added to the tokenizer which converts "\n" into a newline and results in a nicer-looking workspace when saved.

Fix a typo in a file name that blocked the full test pass from running.
