Revert "renamed files; this one is no longer needed"

This reverts commit 26a9fd34892b977d0ae7f9f0c6f8b85267d39d8f.
fix memory leaks in tests
database code fixes

make the return values of  Exec() and ReExec() be
consistent
fix wxWidgets assertion

assertion was due to string format with an unsigned int
lint feature enhancements

don't attempt to check files greater than 5 MB, these files
generate a big AST and can cause the system to run out of
memory

stop accumulating lint errors when there are more than 100
errors in a file (per each lint check type).  There is no
way the user will go through each one, and makes the program
more resilient.

add a button to show lint suppressions from the lint
results panel.
