- Take into account the new modules (PullToRefresh, SmoothProgressBar)

Fix #366 : [Wishlist] Allow Mpdroid to connect even if no network connection is detected
- Do not check if the device has internet connection, just try to connect.
If no network is available, the error connection popup displays a message like "Unreachable Network".
The error message appeared quickly during tests without network.

The cover progress bar is now invisible by default.

Update Gracenote API Endpoint
Attempt to fix the max connection issue
- Do no connect MPD if it is already connected (may happen at app start when 2 views ask for a connection)

- Use only 3 connections (instead of 5) for commands
- Decrease the socket timeout on the status connection for it to be closed
  quicker
