Hide 'ongoing' Posts and add change status of post from ViewPost

[LeanKhan]

• On the Feed only fetch posts that are not in 'ongoing' that is, in progress.
• Users should be able to change the status of a post depending on how they think it went.
  I think it should be the guys receiving that do this. Since its then that know if it was completed.

Partially done, now users only see 'pending' posts.

• There should be a 'complete' button, or something like that :)
