US7 - Sort Itinerary by Date

Value proposition

As a backpacker I want to sort my POIs (points of interest) by date In order to keep track of all my plans

[x] At the top of the itinerary the user sees thumbnails for the POIs they saved on the suggestions page
[x] Below that all the dates of the trip show up
[x] If the user clicks on a thumbnail a popup shows up where they can enter a date (mandatory) and a time (optional)
[x] The item then shows up in text form under the respective date
[x] Each day has an input field for a new item (mandatory) and a time (optional), where the user can add additional POIs

[x] Create a branch feat/itinerary-by-date
[x] Create an overview with all the dates the user entered for that specific trip
[x] Show Thumbnails of all POIs the user selected above the dates
[x] Create a pop up for each thumbnail where the user can type in date and time
[x] Make the POI's name show up under the respective date after the user submits date (and time)
[x] Create an input field for each day where the user can add additional items (and a time)
[x] Add those custom items to the respective date after the user submits item (and time)
