Initial commit. Status so far:

- Parser and output modules are thoroughly tested and working.
- Most LSL immutable functions are working; some not tested; llJsonSetValue not implemented.
- Parser recognizes the following flags that alter syntax:
   extendedglobalexpr: Allow full expression syntax in globals.
   extendedtypecast: Allow full unary expressions in typecasts e.g. (float)~i.
   extendedassignment: Enable the C assignment operators &=, ^=, |=, <<=, >>=.
   explicitcast: Add explicit casts wherever they are done implicitly, e.g. float f=3; -> float f=(float)3;.
  Of them, only extendedglobalexpr is useless so far, as it requires the optimizer to be working.
