Add FAQ to the documentation or wiki

[Kian-Esmaeilpour]

Thanks to @sebastianflorica for the suggestion.
Having a place to document the FAQ from #dev-tradeshift-ui can be really beneficial for developers.
Some stuff like integration with react and angular or how to use attributes with . in jsx can't be fitted anywhere else in the documentation as far as I can see.

Having it as a page in ui.tradeshift.com
OR
Create a wiki page
are two places that I can think it can live!
And for sure link to it in the intro page of the documentation website
