[$80] Delete Capability: Items in "New" Status

[acshields]

If an item (challenge, task, F2F) is in "New" status, the user should have the capability to delete it.

• On the "all items" view for the project, items in "New" status should display a delete button.
• If the user clicks into the item (i.e. the set-up screens), at the bottom they should see a "Delete" button.

@vikasrohit I'm suggesting showing a standard browser confirmation window for this action instead of custom dialogs. Because our current implementation of dialogs requires a lot of code to write.

Sum up:

• Add red "Delete" button in the challenge list, but only for new challenges.

  

• It should be only shown on hover similar to "Active" button for Draft challenges.

• When we click "Delete" show a confirmation dialog similar to when we click "Acitve"

  

  It should work similar to when we activate:

  • if we confirm, show "processing"
  • show red error if error happens during API request. we should be able to click "Confirm" again and try deleting again.
  • when successful close dialog and remove challenge form the list without list reloading

• We also have to show "Delete" button on the challenge editing page

  

• When we click it, show a confirmation modal, same like on the list.

• As soon as challenge is deleted redirect to challenge list page.

• When we delete challenge successfully from any place show a green "toastr" message: "Challenge deleted successfully".

We already modal implementations in place @maxceem, you can reuse them. We are showing such modal confirmations for Activation of challenge as well. Lets keep the UX same for this feature as well.
