To do:

[x] Remove "message" button if the owner of the adv is equal to the requester
[x] Add popup to make a user "request" the timeslot and another one in the owner to "accept" the timeslot
[x] Better format of the date under the messages
[x] If a user accept a request, that adv must be set as sold and no one can open further requests (or see it in the home)
[x] Clarify the "requester" for incoming request and "owner" for my requests
[x] Add a popup for the requestor to confirm the request, then the owner has to accept. Both popup have to check money
