Comment:

 I've been working on restructuring the new {{{IntroducerClient}}} so that
 we can implement multi-introducer grids without losing announcement
 deduplication logic in the client. My work so far is here:
 https://github.com/lebek/tahoe-lafs/compare/master...68-multi-introducer

 The way configuration works is a new {{{[client]introducer.furls}}} option
 which takes multiple values (whitespace or line break separated). If both
 {{{[client]introducer.furl}}} and {{{[client]introducer.furls}}} are set
 the values are appended.

 All introducer tests are passing at the moment, so theoretically this
 might work already. I'm still working on new tests specific to the multi-
 introducer setting. I also still need to make announcements idempotent in
 the introducer. Finally, I'll import Faruq's patches to the WUI and
 documentation, they shouldn't require much modification.
