2017-07-06	Fix many warnings-as-errors issues.	Tim Foley
	The code should now compile cleanly with warnings as errors for VS2015 with `W3`. Most of the changes had to do with propagating a real pointer-sized integer type through code that had been using `int`.
2017-06-29	Overhaul `RefPtr` and `String`	Tim Foley
	- `RefPtr` no longer tries to have distinct cases for interal-vs-external reference counts. Instead we always require an internal reference count. - Types the used `RefPtr` but weren't `RefObject` were made to inherit `RefObject` - The `ReferenceCounted` base class was removed, so that only `RefObject` remains - Implicit conversion from `RefPtr<T>` to `T` added - This created some complicates for other types that relied on implicit conversions, so this isn't a net cleanup right now - The main type that got messed up by the above was `String`, which previously held a `RefPtr<char, ...>`. This change thus also* includes a major overhaul of `String`: - `String` now holds all its data via indirection, using a `StringRepresentation` that is a `RefObject`. This object holds a length, capacity, and directly stores the character data in its allocation. This means that `sizeof(String)==sizeof(void*)` - It is now possible to directly mutate a `String` by appending to its representation (we just need to ensure it has a reference count of `1`, possibly by cloning it). This means that `StringBuilder` is now basically just an idomatic use of `String` - A couple operations that just return sub-ranges of a `String` now return `StringSlice` to avoid allocation when it isn't needed. This required more work. - Indices into strings changed from `int` to `UInt` (which is pointer-sized). This had a bunch of follow-on changes because the value `-1` sometimes needs to be special-cased in code that uses indices. Further cleanups are probably needed here.
2017-06-15	Remove more "core" code that isn't used.	Tim Foley
	It is always easier to add back code when you need it, than it is to maintain code you aren't using.
2017-06-15	Rename `CoreLib::*` to `Slang`	Tim Foley
	Getting rid of more namespace complexity and stripping things down to the basics. This also gets rid of some dead code in the "core" library.
2017-06-09	Initial import of code.	Tim Foley
