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
The purpose of moving the EXEs is so that they are not captured in the
build artifacts. They would be nice to have, but they end up being a few
hundred MBs in size so much too large to bother saving.
These tests use a variety of sample code (with some of the larger files
removed, so they are not complete!) and verifies that they all compile
successfully.
