Updated offerF, Routes, Frontend, bankOffer. don't merge everything.

Btw don't merge everything. My repo isn't same as yours. I don't know which modifications you made. 

Updated offerF-foreachloop, Routes, Frontend, bankOffer. I couldn't test offerF. also for bankOffer our json structure should be like this. 
The comment array should hold offers. I guess.
