Merge #153
153: add "nightly" feature; replace hint::unreachable_unchecked with a panic r=korken89 a=japaric
this implements the action plan described in #149
to give you a sense of the overhead of this change: it has increased the binary
size of some of our examples by up to 10% but this is mainly from pulling in a
panic handler that does formatting
r? @korken89
