Fixes: Some dialog icon issues

The Window Icons were not being used for profile_preferences dialog or
for the Central Debug console.  In the former it transpires the icon
was loaded from a relative file reference and not from the resource
file (and also for the icon for mudlet_custom_exit_properties) file;
and in the latter it was being set by code from the mudlet class which
just did not work - as it is being used as the central widget inside
a QMainWindow widget and THAT is what has to have the icon set!

Also, fix the fact that the profile preference was not opened in the
first tab but the third.
