Dinant

* Implement `capture=True|False|str` for all atoms and user defined expressions.
* Moved `debug()` to its own method.
* Implement `re(name='bar')`.
* Implement `re(times=[...])`.
* `at_least()` and `at_most()`.
* Documentation!

* `Dinant.match()` has a debug mode, where it either returns the first sub expression that doesn't match, or raises the syntax error that makes the regexp fail.
* `regexp()`, so you can pass a raw regexp.
* `text()` is the same as `then()`.

* `then()` is deprecated, just use strings and `+`, like `'C-' + exactly(8, digits)` or `one_or_more(digits) + '°'`.
* `groups()` and `group()` are methods with same semantics as `re`'s.
* Added `hex`, `hexa` that matches hexadecimal digits.
* Support broken day representations like in `Apr 7 07:46:44` (it should be `07`).

Not much, just added a couple of shorthands for matching integers and floats.
