FMSLogo Code

Add a rudimentary implementation of autocomplete for procedures.

Fix the comments to indicate that this file is specific to FMSLogo, not the standard Scintilla.

Remove some conditional compilation that was added to work around
a bug in GTK wxWidgets 2.8 which no longer exists in wxWidgets 3.0.

Fix a bug where printing a very long line did not end up with the commander history scrolling to the bottom.

Fix a regression that was introduced during the upgrade to wxWidgets 3.1.0 where the commaner input would retain its horizontal scroll position when its text was replaced. This was especially bad when a long line was replaced by a short one, in which case the new text might not be visible at all.

Fix a build break when compiling with WX_PURE.

Add UI automation to the editor tests to relieve some of the manual burden when running a full test pass.

Add UI automation to the STEP tests to make it easier to run a full test pass.

Fix bug #319; SETACTIVEAREA now throws a recoverable error when given points that define a zero or negative area rectangle. Before, the error was not recoverable.

Also extend the ERRACT test infrastructure to support testing giving a command bad input (before, it requires that the bad instructions output a value). This involved rewriting some of the existing callers.

Fix the test to pass integers to SETACTIVEAREA, now that SETACTIVEAREA throws an error when given non-integral numbers.
