v3.1.1

Release v3.1.1

- README: document timestamp() and the std::string conversion, show the DATA
  struct fields, add a usage example, note the supported platforms (it is no
  longer Linux-only), and drop the incorrect claim that DATA has an ostream
  operator (only uptime_t does)

v2.0.0

Next generation of uptime_cpp

Now more fetching of uptime value on every call, instead makes a timepoint on it on constructor.
Downside is that there is more to calculate, but for that; there is data() member function to calculate
all fields at once.

Also, it's now more portable. Unfortunately I have no possibility to test it on other architectures except
Linux and OS X; but it should work on others as well.

v1.0.0
