#1 STZ import corrupts data

[Anonymous]

If you have a regatta open and try to import an STZ
file corresponding to an existing regatta, then the
entries and race results from the STZ file are imported
into the current regatta after dismissing the
error/warning dialog.

For example, you have previously created regatta's A
and B (via imports or manual operations -- it doesn't
matter). You have regatta B "open" and attempt to
import an STZ file containing data for regatta A.
Regatta A's entries and results data will get imported
into regatta B.
