Comparing a String with a Dynamic depends on the static types #97

In include/hx/LessThanEq.h the string branch fires whenever either operand is statically a String, so a statically typed String compared with a Dynamic holding a number or Bool compares their string forms: ("5":String) == (5:Dynamic) is true while ("5":Dynamic) == (5:Dynamic) is false, and ("true":String) == (true:Dynamic) is true where JS and eval give false. A Dynamic operand should go through the runtime type dispatch.
