Add delete folder button to web UI

[tiwilliam]

This will add a Delete folder button to all folders, it will be disabled for the root folder. The delete request passes ?recurse and will delete all underlying keys and folders. It might be a good idea to add a confirm dialog for this action in the future.

Resolves issue #102.

There seems to be a issue when deleting a child tree:

DELETE http://localhost:8500/v1/kv/1/2/?recurse

will remove /v1/kv/1, is this expected behaviour?

[tiwilliam]

Hm, this API call:

DELETE http://localhost:8500/v1/kv/1/2/3/4?dc=dc1

will remove everything below /v1/kv/1 as well, including 1 self.

@tiwilliam The "folder" view is just imposed by the UI. There is no actual folder structure. So if the only key is "1/2/3/4" and that key is removed, then those "folders" also are removed. Does that make sense?

[tiwilliam]

Alright, will re-work this to make sense.

[tiwilliam]

@armon Thanks for explaining! This should now work as expected and redirect to nearest existing parent on delete or pop back to root if needed.

Great! I would say we should do a isRoot:hidden in the buttons {{bind-attr class}} instead of disabling it. Just makes it clearer, I think.

I also noticed we're not actually rendering the {{errorMessage}}. I'll fix that post merge. Can you rebase this against master? Thanks, great stuff.

[tiwilliam]

Rebased against master. Yeah, hidden sounds like a better idea, leaving it at disabled for you to change post merge.

[pearkes]

Great, merging.
