Result styling

[Artoria2e5]

The current implementation centers the result and renders in some Math-y serif font, which is not necessarily the most readable thing on screen. Ncalc should consider:

• Right-aligning the result
• Using a sans-serif for result (https://tex.stackexchange.com/questions/77932/the-right-way-to-get-sans-serif-math)

Additional issues include size and line-breaking, both of which appear not quite easy to address for now.

Agreed, it looks very ugly and out of place (for simple equations at least). Maybe provide a font option for that too?

PerKhan/KaTeX#123 suggests that this thing can be hard-done by finding a font and changing the metrics. No switching feature is available it seems.
