FMSLogo Code

Update the expected test log with the output from test cases that were recently added.

Rework int_arg() so that it doesn't modify the arguments list.
This is part of a larger effort to simplify the code base by reducing the number of side effects.

Rename CLogoCodeCtrl::Replace to CLogoCodeCtrl::ReplaceText and make it non-virtual to fix a -Woverloaded-virtual warning.

Add missing "const" qualifier to CanCut and CanCopy so that they override the virtual functions in wxTextCtrl.
This required a little rework to a helper function IsTextSelected() to make it const, as well.
This fixes two -Woverloaded-virtual warnings in gcc.

Refactoring: Change "int macro_flag" to "bool is_macro" in define_helper.
The caller that passed the third state of -1 now calls make_procnode_from_body_list().
This makes the code simpler.

Refactoring: Extract make_procnode_from_body_list() from define_helper.
It is the only portion of define_helper() that anonymous_function uses.
This is a step toward removing the tristate "int macro_flag" from define_helper.

Refactoring of define_helper:
- add clear variable names instead of reusing args, arg, and val.
- move variable definitons to where they're used
- restructure into three major parts

This moves the code closer to being able to get rid of the tristate macro_flag.

Add more regression tests for DEFINE.
This was done to prepare for some refactoring in define_helper().

Replace TRUE with 1 and FALSE with 0.
In this case, the value isn't treated as a boolean, so it's not correct to use TRUE and FALSE.

Refactoring: Use true intead of TRUE when calling compare_node().
It accepts a bool, not a BOOLEAN.
