- implemented string concatenation
- simplified a lot of code
- added many more tests: can now parse all *.go files I got my hands on

(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.

	type T struct {

and

	type T *struct {
		next T
	}

are valid without needing forward declarations.

add "type T struct" syntax for forward struct declarations.

add "type T interface" syntax, but commented out
