Title: Add line/column tracking to parser

* Compiler-AST/Node: new member to store position of Node
* parser: emit line/column information and store it in each created Node instance
* parser: regenerated with `--track-line-and-column` flag
* boot.js: fix `_st()` method to return `nil` if passed in value is `null`
