a303ef2066 Unfold all assignment+operation operators to optimize them better. 
With test case.

cb66f1ff4e Make if ... else if ... chains iterative, rather than recursive. 
Should save some stack if the chain is long.

e5714eba25 Fix the obnoxious issue with globals propagation in full expressions. 
Fixed by backtracking in the parser, and keeping a copy of the original expression if it's a simple_expr, which is used for output in place of the folded one.

There's still the potential issue that if a global is optimized away, then it will "come back" during output and cause an error because the definition is missing.

2cbed52bf7 Add optimization of declarations. 
integer a = 0; -> integer a;
float f; -> float f = 0;
vector v; -> vector v = <0,0,0>;
rotation r -> rotation r = <0,0,0,1>;

6ec39aa745 Add a bunch of optimizations. Fix || and && results. 
Notably, addition/subtraction, and llGetListLength -> !=[]

But also parenthesis removal etc.

With test coverage.

3ac4bc4f0d New option to optimize float-to-int conversion separately from sign optim. 
The option is optfloats. Add support everywhere.

d1bbe26c49 vector v;<0,0,0>-v; triggered EParseTypeMismatch. Fixed. Also minor fixes. 
Convert the self.__class__, which was terrible syntax, to the respective classes in the exceptions.

Fix the EInternal hack in the buitins.txt parser.

fb68273eed Turned everything upside down, and fixed a couple bugs. 
Bugs fixed:
- %= and the new assignment operators were not emitting error on invalid types.
- List globals referenced in another global were duplicated entirely.
- Properly recognize -option in the command line.

Rest:
- Complete overhaul of the internal data structure.
  - Got rid of the symbol table plus mini-trees, and made everything one big tree plus an auxiliary symbol table.
  - No more special case hacks like using tuples instead of lists...
  - Got rid of the EXPR hack.
  - Dict-based, rather than list-based. Allows adding arbitrary data to any node or symbol entry.
- Added a few coverage tests for the new code.
- Return values can now be chained; the functions parameter requirement is gone. Still not fully convinced, though. My guess is that a parser object should be passed between functions instead. Will do for now.
