Remove the tumblr content label

tumblr's content label system sucks. if it has one (which far too many posts do), you often just cannot access it. that's why I made this basic userscript (heavily commented if you don't trust it) to allow accessing them easily. to install it, install tampermonkey (or another userscript manager but tampermonkey works well) and then click this link and it'll pop up with a menu for you to install it. yay! if it doesn't work in some scenario, make an issue in the github here and i'll try to fix it.
