Get posts by main tag

I’ve some sections in the homepage, each one has a number of posts by tags, but if one post have more than one tag, it appears on several sections.

In order to avoid add an additional argument exclude_tags or main_tag on {{#getPostsByTags}} helper, i suggest create an {{#getPostsByMainTag}} helper.

I think that if the pages-feature came to reality, this is no longer necessary.

```
let themeHelpers = {
    getPostsByMainTag: function(mainTag, content) {

        const postsData = JSON.parse(JSON.stringify(content.data.website.contentStructure.posts));

        let filteredPosts = [];

        postsData.forEach(function(post) {

            post.mainTag.slug == mainTag && filteredPosts.push(content.fn(post));
        });

        return filteredPosts.join();
    }
};
module.exports = themeHelpers;
```
