haven't figured out how to catch yet, so the settings need to be valid :)
basic ability to test sql statements for a connection
adding files for transforms
more progress on transforms

added naive ability to query table schema, working on mapping components
progress on defining table transforms
working on dropdown input
add ClickOutsideMixin to close dropdown input
fix style handling, more work on input dropdown
toggle dropdown with alt+down
starting the actual transform work
adding task to perform the actual data transforms
basic support for copying data is working
record count updates

display count for source and target tables and add explicit option to
truncate the target table (the transform no longer implicitly does this
to allow cases where multiple sources are merged to one target)
