[API docs] Utilize template for docs

[Garry Yao]

JSDuck allows customized template:

jsduck --template=PATH              Dir containing the UI template files.

The default template is available [here ​https://github.com/senchalabs/jsduck/tree/master/template] thus can be extended on our demand.

#9277 is to re-fixed by this ticket.

Opened review request t/9338 on dev, the directory under dev/docs/template/ is an ExtJS application which desires a separate GIT internal repo, and referred by the dev/docs using sub-module, after the review.

I don't think we need this kind of customization at this stage of development.

I might be useful as it makes the documentation to work under IE8.

[Piotrek Koszuliński]

IMO we don't need this kind of customization right now. The cost of maintaining our copy of JSDuck's templates files plus additional sub-module just to fix one minor thing (which JS dev uses IE8 on a daily basis?) is too high.

Let's use this experience for some more serious issue in the future.
