* For a `#error` or `#warning`, read the rest of the line as raw text to include in the error message
* When skipping tokens (e.g., in an `#ifdef`d out block), don't emit errors on invalid characters
* TODO: we could clearly get more efficient and skip whole raw lines in the future
* Fix an issue when a macro invocation that expands to nothing (zero tokens) is the last thing before a directive. The preprocessor was returning the `#` as an ordinary token, because it has already gone past its test for directives.

Fixes #380
The `#import` directive was a stopgap measure to allow a macro-heavy shader library to incrementally adopt `import`, but it has turned out to cause as many problems as it fixes (not least because users have never been able to form a good mental model around which kind of import to do when).
This change yanks support for the feature.

These had a typo (`Literial`), so they needed a fix eventually.
I also went ahead and made things a bit more verbose (`IntegerLiteral`, `FloatingPointLiteral`) because these names don't get used often enough for the brevity to pay off.

Right now `#import` only differs from `#include` in that it takes a string literal for a file name instead of a raw identifier (to which `.slang` gets appended).
The next step is to make `#import` respect preprocessor state, while `__import` doesn't.

The basic idea of this change is that user code can just write:
#include "foo.h"
and then if `foo.h` gets found in a list of registered directories for "auto-import," then it actually gets interpreted as if the user had writte, more or less:
__import foo;
That is, the code in `foo.h` will be treated as Slang, and will be fully parsed and checked (no matter what the source language had been), and the scoping rules will be those of `__import` instead of `#include`.
This is a really big hammer, and I could imagine it smashing fingers if used poorly.
I'm not sure this feature will pan out, but we need to try things to know.
One big piece of that that I'll likely keep in either case is an overhaul of command-line options parsing for `slangc`. In particular, this logic has been moved into the core `slang` library (so that users can just pass options in via the API), and it is all done on UTF-8 strings rather than wide strings (which was always going to be Windows-specific).
