Futago-za Ryuu 21a6de06d5 Optional features
This commit enables optional features that are enabled by default in the generated parser.

For now, only some of the helpers and filename are generated based on this new option, but this will change in the future most likely.

Resolves #421

Futago-za Ryuu fedf0f3480 Resolve 'vm.runInContext' bottleneck
Calling 'vm.runInContext'  is slightly more expensive then calling `eval`, but removing the string template and extracting the variable generator helps abit.

Futago-za Ryuu ef0595596f Implement error emitter (Closes #431)
Along with commit 851d8ed, this resolves #431 based on the fact that plugins can overwrite session methods, allowing use cases like multiple or limited errors (and/or warnings) to be an opt-in feature.

Mingun 0dab14d652 Add ability to extract comments from the grammar (#511)
All comments stored in the `comments` property of the `grammar` node.
Comments extracted only if the `extractComments` options set to `true` when you generate parser.
This property is object with mapping start offset of comment to comment object, that looks like:

```js
{
  text: 'text in the comment, just after // or /* and before */',
  multiline: true|false,// true for /**/ comments, false for // comments
  location: location()
}
```

Futago-za Ryuu f5b323b401 Report consistent errors on look ahead + cached results
This should resolve issue #452, and is based entirely on a fix @nikku did on a local branch of PEG.js v0.10.0 (Currently at https://github.com/nikku/pegjs/tree/452-peg-js-0.10-fix).

Also his test case from #555 is included.

Fixes #452, Closes #555

Mingun 9b90fa1d81 Move all codegeneration from `generateBytecode` pass to `generateJs` pass (#459)
* Split 'consts' collection by content types into:

  - literals: for literal expressions, like `"a"`
  - classes: for character class expressions, like `[a]`
  - expectations: for constants describing expected values when parse failed
  - functions: for constants with function code

* Move any JavaScript code generation from 'generateBytecode' to 'generateJs'.
* Rename opcode 'MATCH_REGEXP' to 'MATCH_CLASS' (name reflects purpose, not implementation).
* Replace 'PUSH' opcode with 'PUSH_EMPTY_STRING' opcode because it is only used with empty strings

Futago-za Ryuu 7a19d46e8a Add the ASTVisitor class (#451)
For compatibility with pre-0.11 plugins, this class lives on the same namespace as the orignal visitor helper and also exports a static method called 'build'.

Futago-za Ryuu 93cc6c5b26 Parser calls AST node creator now
Before this commit, the PEG.js parser always created the AST using a plain JavaSctript object, but allthough simple and effective for the job, this method sacrificies performance slightly.

From now on the parser shall call a Node creator. This should help with performance, as well as in the future move some AST helpers into the new AST functions.

Futago-za Ryuu 7cdfc03e9f Added utility methods for objects
Before there used to be some internal utility methods for arrays and objects, but as the code base moved to ES5+ use  case only, these were removed in favour of native alternatives, but most of these were only beneficial for arrays.

This commit add's common utility methods for objects, and also exposes these as they can be used by plugin developer's on the PEG.js AST.

Mingun 4cc9185a78 Improve error when reserved word used as label (#552)
Before this commit error looks like (for input `start = break:'a'`)

> Expected "!", "$", "&", "(", "*", "+", ".", "/", "/*", "//", ";", "?", character class, code block, comment, end of line, identifier, literal, or whitespace but ":" found.

After this error looks like

> Label can't be a reserved word "break".
