asarium 016c07dc3a Add feature to execute Lua coroutines at specific points
This adds a mechanism for running generic operations at specific points
of the frame execution. This can be used by any part of the code an not
just Lua since it simply executes std::functions. It also adds an
"execution context" concept that specifies in which situation an
operation should be executed.

This is then used by the Lua Coroutines code for resuming coroutines at
specific points instead of always when the awaited promise resolves.

asarium 08c6e0d072 Introduce error state of promises
This is necessary after all to properly clean up resources if an
operation becomes invalid.

Also bumps Visual Studio version to 2017 on Appveyor.

asarium ebcf686cf7 Add Lua API for promises and async coroutines
This adds a Lua API for representing asynchronous operations and running
coroutines based on those operations comfortably. This is very similar
to features other languages have introduced such as C# or JavaScript. In
fact, the whole "promise" thing is derived from how JavaScript
represents these operations.

This is the initial and very basic system for supporting async
coroutines in Lua. There is no native support for running these
operations at specific points (they run whenever the awaited promise
resolved) or making sure they do not leak through different game states.
