Make tagged documents data available as global data.

[manikmagar]

As of now, only alltags is available globally and it only contains String list of tag names. For one of the blogs, on home page, I want to show number of documents in each tag, which doesn't seem possible or easily achievable. May be alltags can return list of Tag model where Tag object could be a map of { "name" : "test", "noOfDocuments": 30, page-url: "{name/sanitizedname}"} or more elements.

I can write a script in template to iterate over published_posts or published_content and then get the stats but that will slow down rendering along with adding other scripting complexities to templates.

P.S. I actually wanted to show categories and their post count but until #293 is available in release, I am choosing tags. Although, even categories then should be made available globally with more data elements.

For the number of tagged posts, this one seems to be duplicate of #216 .

Accidentally closed it while adding previous comment, I will keep it open for review to see if more data about tags should be exposed? I am going to use the solution specified in #216 .

Jup. That would be nice. I think a refactoring to a better data model abstraction is the right way to go.
