+ have resulted.

+- The obsolete hub option from server info has been removed.
+
+### docs

+ stuff has been renamed and shuffled around to be more consistent.
### code
+- irc_dictionary and irc_radixtree stuff is now in librb, prefixed accordingly.
+ Typedefs have been added for consistency reasons. For example, now you would
+ write `rb_dictionary *foo` and `RB_DICTIONARY_FOREACH`.
+- C99 bools have been added. Don't use ints as simple true/false flags anymore.
+ Accordingly, the `YES`/`NO` and `TRUE`/`FALSE` macros have been removed.
+- libratbox has been renamed to librb, as we have diverged from upstream long
+ ago.
