Code to make clients fetch and use microdescriptors for circuit building
To turn this on, set UseMicrodescriptors to "1" (or "auto" if you want it on-if-you're-a-client). It should go auto-by-default once 0.2.3.1-alpha is released. Because of our node logic, directory caches will never use microdescriptors when they have the right routerinfo available.

+ o Major features
+ - Clients can now use microdescriptors instead of regular descriptors
+ to build circuits. Microdescriptors are authority-generated and
+ -authenticated summaries of regular descriptors' contents, designed
+ to change very rarely. This feature is designed to save bandwidth,
+ especially for clients on slow internet connections. It's off
+ by default for now, since nearly no caches support it, but it will
+ be on-by-default for clients in a future version. You can use the
+ UseMicrodescriptors option to turn it on.
