add quit button and fallback text

adds fallback text to the buttons so they show up if you do not have any qt themes installed, such as if you are an austere weirdo who runs i3 on gentoo (btw). also added a quit button, it is tiny and right next to the refresh button. only the finest in interface standards!

i have no idea why i cant like, change the files i am merging oh god why are there 13
