Add a button to delete individual offers for gig requests

[Guest jagjgjg]

As a gig buyer here is a suggestion to improve the gig requests feature:

after you click your request on manage_requests and see a list of them, there should be a delete button.

it takes some time to sift through all the requests for the ones you are considering and it is easy to forget which ones you like and which ones you are sure you do not want to order. it would increase speed and efficiency thanks
