Fix assignment priority
...
The assignment operator is lower priority than any other binary
operator.
Otherwise the following:
```tiger
a := b | c
```
Would be parsed as:
```tiger
(a := b) | c
```
Instead of the expected:
```tiger
a := (b | c)
```

Add meta-variables
...
This is an EPITA extension of the language, used mostly by internal
compiler machinery.

Replace '_typed_field' by more specific grammar
...
Instead of re-using a common rule, inline its definition and use
'_field_identifier' where appropriate.
This is useful for more accurate high-lighting.

Add support for nested comments
...
Unfortunately, the 'extras' array expects single tokens only, so one
can't really use a recursive parsing rule to express nesting comments...

Add comments
...
For now it only supports non-nested comments. It seems like I *will*
need to write an external lexer to account for nesting properly.
