Fix the operator precedence in expr. expr now uses the precedence table specified by POSIX, implemented using the "precedence climbing" algorithm. See the references at the top of eval_expr(). This fixes 3 of 4 failing tests. I also added more tests for correct behavior and for syntax errors. This includes a new test exposing a segfault, related to type coercion.
