French language little fix on video.properties.

[PoorPocketsMcNewHold]

Here's a couple of little fix for this file.

• I've added an insecable space to the line decSped and incSpeed due to how numbers should be written in French.

In French, a space is required both before and after all two- (or more) part punctuation marks and symbols, including : ; « » ! ? % $ #

The unbreakable space is used, among other things, to avoid separating a number or number written in numbers from the name or symbol preceding or following it. It is mainly used in [...] before the percentage symbol.

• I've changed the word translation of resetZoom, as Reset is an English word. The correct translation in French would be Réinitialiser

Verb réinitialiser 1 to restart 2 to reset

https://en.wiktionary.org/wiki/réinitialiser

Réinitialiser IPA: /ʁe.i.ni.tja.li.ze/; Type: verb; リブートする 再起動する リセット { Verbal; Noun } リブート { noun } 再起動 { Verbal; Noun } リセットする { verb }

• I've modified the term "roulette" in reverseWheelMediaSeeking. Since it's already translated as "molette" (Actual translation of that part on a computer mouse) I've decided to use that one as well.
