#### PHP 7.3 RFC https://wiki.php.net/rfc#php_73
We need to support the following features: 1. [Allow a trailing comma in function calls](https://wiki.php.net/rfc/trailing-comma-function-calls) 2. [list() Reference Assignment](https://wiki.php.net/rfc/list_reference_assignment) 3. [Flexible Heredoc and Nowdoc Syntaxes](https://wiki.php.net/rfc/flexible_heredoc_nowdoc_syntaxes) I've supported No.1 and 2 in this PR. Main changes are `php/php.editor/tools/ASTPHP5Parser.cup` and `php/php.editor/src/org/netbeans/modules/php/editor/verification/PHP73UnhandledError.java`. Other than those, I added unit tests. However, No.3 is not easy because of BC break. Probably, we should create a lexer(and parser, too?) for PHP 7.3, but I suppose unit tests will be complicated. (We are using the common lexer and parser for all PHP versions, so far.)
