Having two separate files for the compile output is just too confusing,
and it adds an extra file users need to look at and give us when there
are issues. This change simply makes qb64.bas send both the stdout and
stderr output to compilelog.txt.
Fixes: #61
windres has a handy feature of allowing us to feed it an executable and
it will give an error code depending on whether that executable has a
resource section or not. We can use that feature to create a quick test
to verify the distributable has the resource information on it.
