Fixed Some Grammatical errors in README.md

I consider only the "trademark" as a good change. Fixing "Poweroff" to "Power off" and "virtio" to "virtual" looks like nonsense. In the first case, a specific device is meant, and in the second case, a certain class of virtual devices is meant, called "virtio" (e.g. virtio-net, virtio-blk, etc).

Looks like a bot. Also trademark writed because in Russian its a two separated words.

Choosing "trademark" over "trade mark" is just a difference of spelling in UK and US, same as color/colour.
