[PATCH 1/9] MainWindow: prevent a possible crash on "re-plan"

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

MainWindow::on_actionReplanDive_triggered():

If a dive in the divelist does not have a "DC Model" for some reason,
selecting "re-plan" from the menu will pass a NULL value
current_dive->dc.model to strcmp() and break before the debug output.

To fix that we check if the said .model value is NULL.
