Submodule version seemed to be out of sync with main repo.
- WebDAV mounting should now work on non-pool VMs (tested on huygens.massive.org.au).
- The last-used hostname for the CVL tab's "Other..." connection is now saved.

- WebDAV-mounting and file browser window opening have been split into two separate events.
- The WebDAV-mounting command (gvfs-mount) is now forced to complete (pexpect waits for EOF).
- Added a check for the exit code from WebDAV mounting command if available.
- Removed unnecessary multiple updates to progress dialog value during WebDAV mounting.

- runLoopServerCommandThread now breaks out of its loop when it finds a match.
  - I don't understand why this was necessary, but I found cases where
    stdout.splitlines(False) appeared to give multiple copies of the same line of output.
- Additional logging info for runLoopServerCommandThread when timeout is invoked.

- Fixed sanity check's progress dialog value (so gauge doesn't jump forward then back).
