1. Unary-Pre operators detection fixed.

Browse source 
2. Unary Minus operator added (now legal, worked before?).
3. GetReference operator (&). For example (a=&b; *a=3;) will set b=3.
4. Operators precedence added (C-like), much more intellectual expressions parsing.
5. Functions redefenition added, use "#name", like "func()(1); #func()(2);".
