[Cuis-dev] A few tweaks to preferences

[Juan Vuletich]

Hi Folks,

After some off-list discussion, and the risk of newcomers, especially 
students, get scared after accidentally doing World / Quit and quitting 
without any warning, I did a few tweaks. Now the menu option reads 'Quit 
without saving' and by default asks for confirmation. The confirmation 
can be disabled by doing `Preferences disable: 
#checkLostChangesOnStartUp`, although it will still be given if there 
are unsaved ChangeSets.

I also made the "Save new Release" option also quit.

I also flipped preference #checkLostChangesOnStartUp to false, as I 
expect most people (like me) will prefer manually going over the 
.user.???.changes files to recover stuff.

And as usual, tweaks to VectorGraphics.

Thanks,
