Bug fix: `n-1` was scanned as `n` and `-1`, which was rejected by a style constraint. I removed useless style constraints in the lexer. I removed dead code in `pascaligo.ml`. I added my first draft for the reference manual of PascaLIGO: DO NOT EDIT. Edit the website instead. About the bug fix: This was an awkward attempt at rejecting at lexing time negative integer literals whose sign is separated from the digits, like `- 1`. The fix was simple: remove the `integer` regular expression and use `natural`.
