Add Install Mode to Defense+ popup menu

i think it would be much more intuitive to have Install Mode in the Defense+ popup menu.

Before i discovered how to get out of install mode (i had to ask), i would go into install mode, then popup my
defense mode menu to check if i was still in install mode (it would tell me that i was still in the previous mode –
safe --), then i would run what i had just installed assuming that it was safe to do so.
then the ‘installation mode alert message’ would pop up and i would think eh? i just looked at the defense mode
and it said safe!
of course this was before i found out that you have to go to the main menu and switch to previous mode, its
just not very obvious.
