Clarify build requirements.

The minimum versions are largely bogus, since we do not continuously test them.
Instead, we've been using Abseil's five year guidelines to decide when to rely
on tooling improvements. Document this.

Remove the note on how to build Ninja as that'll just get out of date. For
instance, they appear to support Python 3 when building now.

Explicitly call out that CMake 3.0 will be required next year (released June
2014). 3.0 is the minimum needed to distinguish Clang from AppleClang, without
which version checks on Clang don't work.

Also document that we require a C++11 compiler for more than just tests these
days.
