Now that we have a nice intro screen for the daily challenge, it's
generally thought that we want to "spoil" the beatmap until the intro is
shown.
Also I was never a huge fan of having a tooltip on a main menu button..
just feels a bit odd.
I thought I had fixed this already once but it still looks broken.
Basically when hovering over main menu buttons every now and then it
will look like their backgrounds are not covering their entire width
when they expand.
The removed X position set looks wrong to me when inspecting the draw
visualiser with the element because the element looks to be off centre
horizontally, and removing it fixes that.
