More compile fixes

- Re-removes Bukkit#getServerName - This was (hopefully?) only added back
  for Timings v2. It should be kept in that scope.

- Intend to let PlayerViewDistance API slip. Given the scope of the
  changes in this area it seems best to let this slip past initial
  release. It can be re-added when there is additional time to focus on it
  and the changed systems it relies on. If it is fixed prior to release
  this is implemented as a single shim patch that can be dropped.
