Much more efficient generation of function signatures, updated docs

Browse Source 
This modification taps into some newer C++14 features (if present) to
generate function signatures considerably more efficiently at compile
time rather than at run time.

With this change, pybind11 binaries are now *2.1 times* smaller compared
to the Boost.Python baseline in the benchmark. Compilation times get a
nice improvement as well.

Visual Studio 2015 unfortunately doesn't implement 'constexpr' well
enough yet to support this change and uses a runtime fallback.

- Everything is contained in just a few header files; there is no need to link
against any additional libraries.
- Binaries are generally smaller by a factor of 2 or more compared to
equivalent bindings generated by Boost.Python.
- When supported by the compiler, two new C++14 features (relaxed constexpr,
return value deduction) such as are used to do additional work at compile
time, leading to smaller binaries.
