Slimmed down the panel menu

-Added toggle to show/hide troubleshoot menu, its hidden by default. Really only people who debug/develop need it, other then restart which can be accessed alt+f2 r/resart

-Ridded of "All settings" item, this isn't a launcher, if cinnamon-settings needs to be accessed quickly, a user should put it in their favorite apps in the menu

-Tucked everything else in a popup menu called "More"

-Fixed/changed some labels
