Adds: - UnaryOperator: AST node for unary operators -, ++, --, and so forth - UnaryOperatorOptimizer: optimizes a unary operator with its operand - now integer and float negation, and integer inversion - later x[y]++ to a single instruction Also: - automatically include basic.em, which includes some parameter defaults like -1. This allows the compiler to generate output for a hello, world script with the exact same .ecl output as the legacy compiler.
