Surface Samba connection-specific logs in WebUI

[Hooverdan96]

For samba additional separate logs are created by client connection (I think that's the default setup, unless one mucks around with the smb.conf file) which are not visible/accessible through the WebUI. The feature request is to surface these in the WebUI (possibly using the log display/download facility we already have, or as an click-to-view from a given samba share from the corresponding web page.
