Aul: Correctly check for enable/disable keywords in warning pragma
...
The parser was only checking that the passed setting matched the
beginning of the expected keyword, instead of checking for the full
length. This way, users could write "#warning e" instead of the
expected "#warning enable" and still have it work.

Aul: Throw correct exception on parameter-less warning pragma
...
When no parameter followed the "#warning" pragma, because the end
iterator would be located before the begin iterator, basic_string's
constructor would throw std::length_error. Check for this case
beforehand so we can throw the expected C4ParseError instead.

Revisit #includes

Consolidate the include statements scattered across the code in accordance
with the comment in C4Include.h. The advantages are listed in the same
comment.
Furthermore, it follows llvm-include-order which is the logical
extrapolation of the project's style guideline wherever possible
(C4Include.h being the most-frequent exception).

Aul: use %u instead of %zu for parameter indexes
...
MinGW uses an ancient version of the CRT, which doesn't support the z
modifier for integer types in printf. Use %u instead and cast to
unsigned.

Aul: Allow the user to selectively enable/disable warnings
...
This commit introduces a new Aul directive "#warning", which can be used
to enable or disable warnings for a particular piece of code.
"#warning enable" enables all warnings.
"#warning disable" disables all warnings.
"#warning enable empty_parameter_in_call" selectively enables one
specific warning while not affecting any other.
All warnings that used to be controlled by Developer.ExtraWarnings
remain disabled by default.

Aul: Parse scripts into an AST, then generate bytecode from that
...
This commit contains a fairly substantial rewrite of the C4Script code
generator. Instead of generating bytecode while parsing the script,
we're now parsing the script into a syntax tree, and have any further
processing happen on that instead of the raw source.
At this time, the code generator emits the same bytecode as the old
parser; there are several optimization opportunities that arise from the
new possibility to emit code out of order from its specification by the
author.
Compared to the old compiler, this one is still rather deficient when
dealing with incorrect code; it's also not emitting several warnings
that used to be diagnosed.
