VLCOpenNetworkStreamTVViewController: Add network stream rename feature
This merge request adds:
- A feature allowing users to rename network streams by long pressing the cells and selecting the rename action.
The default name attributed to a network stream is the last component of its URL.
This merge request also brings a fix to the URLs management:
- The stream's URLs are saved, stored, and deleted via the NSUserDefaults when the iCloud-based container NSUbiquitousKeyValueStore is not available.
Closes #1448 (closed)
