Bug 16829: Add 'interface' to the log viewer

This patch introduces the 'interface' filter to the log viewer.

To test:
- Apply the patch
- Open the log viewer
=> SUCCESS: As default, 'All' interfaces are chosen. OPAC, Intranet and SIP are presented
- Do a lot of log searches, verify that the interface column shows what is expected.
=> SUCCESS: The chosen 'interfaces' are kept when rendering results.
