Allow underscores in numbers; better detection of FP
- Allow underscores as group separators in numbers, for example: 0x1234_5678 is now a legal number. The underscore is just ignored, it adds no meaning. - Recognize dotless floating-point numbers, such as "1e30". This entails distinguishing hexadecimal numbers in the scanner, since e.g. 0x1e30 is a perfectly legitimate hex constant.
