Reduced Precision Number Display

[Regisle]

This reduces the number of digits shown, and instead opts to show SI prefixes (k, M, B, T)

I just ended up applying this to everything for now, its much harder to only apply it to dps becouse then I need to tag what does and does not get it applied to, I kept the same level of precision as the base number if it had any, (and 2 decimals if it didnt), I can standardise this to 2 if we want it.

This does not modify the values stored in the xml, only the values displayed in PoB itself.

This does have issues above 15 digits, I can either add more prefixes, or can let it continue in the function through showThousandsSeparators to still get separated, but people shouldnt have numbers that big so I think this is fine

I can cleanup code to not use if statements, but it shouldnt change much, so up to maintainer what they prefer for style

It's definitely more readable, I like it. Though the SI prefix for billions is G not B right? Which makes me think you might want to just stick with semantic prefixes, and maybe all in the same case (my preference would be lowercase). I don't think anyone is worried about Kelvin just yet, maybe next league...
