Manual transmission, tachometer, new hud style

[MelonTasty]

So, as written in thread name, i suggest to add manual transmission with tachometer (and, if it's possible, boost gauge).
With these things i want to do this:

Drift on 3-rd and 4-th gears. But i dont really think that with current car physics it will matter.
And just ride around city on one gear. Or racing with manual transmission.
Also, i suggest new hud style to be like in nfs 2015 remake (there is no sense in custom speedometer anyway).
