Vuesax: font-size in em instead of px

[DRogueRonin]

I noticed that for example the vs-sidebar-item uses a font-size of 15px. In contrast to my other elements that's rather small.
em values should be used there so they scale with everything else.

The same with paddings and margins and everything else that can/should use em.

if you are absolutely right it is better to use em you could do a PR on this where you see pertinent thank you very much
