remove Token::$line
minor #911 remove Token::$line (keradus)

This PR was merged into the 2.0-dev branch.

remove Token::$line

Remove Token::$line due to:
- we don't use it anywhere;
- non-array tokens like ; doesn't have line property set, only array tokens like T_IF have
- when adding new token we don't set line property
- when changing new lines we don't update line of following tokens.

Coming from #907 issue
