FMSLogo Code

Replace some of the command-processing logic with calls to ANSI C library functions. This makes the code smaller and easier to read.

Refactor how the code determines if there's an editor open. Now, the checks have been centralized so that the implementation may change more easily.

This was done as a step toward fixing the bug where the editor is checked by name, regardless of if the editor has anything to do with this FMSLogo session.

Integrate translations of "Apply" and the names of various colors from Daniel Ajoy.

Fix a few problems with the "clean" target where it wasn't cleaning everything it should have been. This was mostly due to the case-sensitive nature of find.

Fix bug #1688926; '-1e-16 < 0' once again outputs true.

The comparison logic for floating point values no longer treats floats within DBL_EPSILON of each other as being equal. Instead, the behavior is now as it was in MSWLogo.

Establish a new baseline, which includes a few more tests and a few bug fixes. Unfortunately one of these bug fixes is for bug #1688926 introduced many more failures in the math test, because floating point numbers within DBL_EPSILON of each other are no longer treated as equal (the bug was that they were treated as equal).

Add regression tests for bug #1688926, which is that very small numbers were treated as equal to zero even when they weren't.

Update the expected version. It's not 6.13..0+.

Add some extra tests for alternate ways of cancelling the dialog box.

Fix bug #1622720; SELECTBOX GUI is now internationalized. This also fixes a related bug where pressing "X" on dialog didn't act the same as pressing the "Cancel" button.

The fix was to replace the OWL TPickListDlg with a much simpler, but less general version that I wrote called CSelectBox. Doing it this way has the added benefit of making FMSLogo a little less dependent on OWL and reducing the code size a little.
