FMSLogo Code

Update the screensaver to use precompiled headers.
This improves build times by 1-2 minutes on my laptop.

Move edit_editexit from fmslogo.cpp to logodialogboxes.cpp.
This was never used by fmslogo.cpp and is used by logodialogboxes.cpp, so it makes more sense to define it there. However, the real motiviation is to fix a bug in the screensaver which re-defined it as char[] instead of wchar_t[] (a regression introduced when porting FMSLogo to use Unicode). By moving it to logodialogboxes.cpp, the screensaver and the main environment can use the same definition.

Update the screensaver to use wxwidgets 3.1.3, like the main environment.
This should have been done for the 8.0.0 release, but I must have forgotten about it.

Fix a bug in UIAUTOMATION.SENDBUTTONPUSHTOWINDOW when a window title given as a list couldn't be found.
Before, it would have an error when trying to log the failure. Now it can log the failure.

Add a stronger warning against using Strawberry Perl
I recently abandoned it after not being able to debug fmslogo.exe with its gdb.

Remove a redundant COPYDEF for ED from the French translation.
This duplicated the translation in localizedstrings-fr.txt.

Ignore the high score file, which is generated by running AM.lgo and should not be commited.

Update the expected test log to account for recent test fixes.

Fix a test bug in MESSAGEBOXTEST.POSITION where the parent was narrower than the messagebox.
This caused the test to log false-positive failures about the message box being positioned to the left and right of the parent on Windows 10, where the message box is wider than it is on Windows XP.
The fix is to widen the parent windows by 100 pixels, which is just enough to hold the narrowest Windows 10 message box.
