#7753: Allow result_of to fall back on decltype

----------------------------------------------+-----------------------------
 result_of uses decltype by default on very few compilers, since most
 current compilers' decltype support doesn't work for some TR1-style usage.

 Many of those same compilers support C++11 lambdas which don't follow TR1
 result_of protocol. Currently, this makes lambdas very difficult to use
 with other code using result_of.

 The attached code allows compilers which partially support decltype to use
 it only on functors which don't publish a result_type or result struct.

 It also contains tests & doc changes. Compiled with VC10, clang++3.1 &
 g++4.5 (both compilers with and without -std=c++0x).
