It seems that without explicit initialization of the members they remain
uninitialized. The lack of initialization caused crashing, because
PavuApplication::on_activate() creates the MainWindow only if mainWindow
is NULL, and if it's some random value instead, on_activate() calls
selectTab() on a non-existent window.

This introduces a new file for clarity. Options
handling changes so that --tab changes the tab
if the window is already opened. Other options
are only used at start time.
