Emended StringToMReal as the current version, moved StringToDouble to end. Added some caveats of important pitfalls.

Keep in mind that Internal`StringToDouble[] can produce unexpected results: "-1" is parsed as -1.0 but " -1" (extra leading space) is parsed as 1.0 (sign dropped). Also "1.0000000000000000" is parsed as 1. but if you add one more zero it returns $Failed["Bignum"] and no message is generated.

@FJRA Why should ToExpression be avoided?

Always try to avoid ToExpression!
