notably, test normal + single + generated + Lua 5.3.5 only once,
then only run the runtime_test and compile_test for normal for all other permutations to help increase text matrix throughput
improve exception documentation
improve state_view default handlers
add SAFE_PROPAGATION defines for compiling C++ as Lua
add examples for automatic operator registrations and as_container
fix tutorial code
change tests to not throw unless absolutely necessary
provide synchronization for file writing in tests
provide thread safety around thread tests for REQUIRE
add ostream automatic support
change 5.1 compat to only kick in luaL_loadbufferx and luaL_loadfilex when LuaJIT is version 2.0.1 and lower
compiler that has full c++ exception interoperability
(http://luajit.org/extensions.html#exceptions), define
SOL_LUAJIT_FULL_INTEROPERABILITY. This will prevent sol from catching
(...) errors - in platforms & compilers than have full c++ exception
interoperability Lua errors can be caught with catch (...) in C++ - in
these cases sol inaccurately prevents Lua errors from being propagated
correctly.
