#190

Adds support for scope/key

This is a minor release, providing support for:

<span>{{scope/person}}</span>

Which is equivalent to:

<span>{{scope.find('person')}}</span>

cloneFromRef includes meta information

Fixes #187

notContext scopes are readable using ../

This fixes an issue where object could not be read using ../object in the following example since object is in a "notContext" scope:

{{#each(objects, object=value)}}
    {{#each(../fields, field=value)}}
        {{../object[field]}}
    {{/each}}
{{/each}}

Scope refactor and variable scopes

PR #182

This creates variable scopes which are useful for making for(of) helpers work in stache.

This also refactors to avoid recursively calling set. Now scope walking all happens in _walk.

This passes all downstream tests, but should be used with a bit of caution until we updated some example apps.

Tolerate walking to a scope that doesn't exist

Fixes #183.

scope.log and able to look up helpers across many TemplateContext
