Fix Bug #385; Deleting the window from the setup callback of WINDOWCREATE no longer reads freed memory.

Replace DebugBreak with wxTrap so that the DEBUGALLOC environment variable works on GNU/Linux.

Fix bug #596; document why SHOW (or PRINT) doesn't include the origin of an array.

Ignore *.gmon files, generated by an fmslogo that is instrumented for profiling (compiled when PROFILE=1)

Ignore files created by "make coverage_report"

Fix Bug #392; RUNPARSE no longer leaks memory.
The return value from parser() was not being freed.

Fall back to writing to stdout in TraceOutput if there's an error writing to stderr.
On Fedora, writing to stderr fails with EAGAIN from the context of atexit handler.
Falling back to stdout is better than ignoring the output, since that makes the debugheap useless.

Add an empty "default" label to a switch statement to silence a warning about unhandled cases of an enum.

Add some comments to po_helper()

Fix Bug #601; PO now displays lines in procedures defined with DEFINE correctly in the Commander History.

The code intentionally didn't print a newline when the WRITER is [] because, when a procedure
is defined with TO, it prints each line using printfx(), which always writes a newline. However,
for procedures defined with DEFINE, it doesn't use that function, so no newline was written.

The fix is a little bit of refactoring that prints the newline differently depending on whether
the procedures was defined with TO or DEFINE.
