No need to unlink the socket - it's in the abstract namespace now.
Fix per connection file-descriptor leak in SocketServer.
Set FD_CLOEXEC on all socket file descriptors (and some refactoring).
Ignore X11 events we aren't interested in (don't print anything).
Make Uncopyable more consistently defined.
Use C++11 auto where appropriate.
Add command line option for traditional-wrapping.
Use uint16_t (instead of uint32_t) for window dimensions.
Bell options: visual, audible, map, urgent.
Remove cruft from config.cxx.
Added option: scrollbar-visible (for showing/hiding the scrollbar).
Cleanups.
