- accepts all Go code (use -s flag)
- complete rewrite of AST, AST building, and printing
(as a result much more compact)
- printing severely screwed up at the moment, but should be
fully working in 1 more day

if in a if, for, or switch header, must be parenthesized
- implemented string concatenation
- simplified a lot of code
- added many more tests: can now parse all *.go files I got my hands on
- printing output currently broken in some cases, use with -s (silent) option

(for instance *p was not allowed on the left side of "="). Changed
to Expression everywhere (this is too liberal, UnaryExpr is probably
good enough, but it seems funny, and we need to check semantically
anyway). This matches 6g yacc.
- Write expression syntac recursively to express evaluation order
and precedence syntactically.
- Organized open issues list, folded in stuff from todo.txt which
is now obsolete.

- allow for empty import, const, type, and var decl lists inside ()'s
- fixed grammar for inc/dec statements
