Enable html_link_suffix

[yotchang4s]

I want to control the extension for internal links.
For example, if you hide the extension using the MultiViews feature of Apache.
This is a patch for that.

Fixes summary

• Change to app.config.html_link_suffix from hard code '.html'(Sphinx has html_link_suffix)
• Add html_link_suffix to MetaData class
• Append html_link_suffix to metadata.link

Shouldn't index also get an extension?

Thanks! Overall looks good though I added a couple of comments. Would be great to also add a unit test that sets the extension to something different than html and then makes sure all files generated have the expected extension.

Thank you for the detailed comments!
I have fixed a point that has been pointed out there.
But I'm sorry... I do difficult to write unit tests because I wrote for the first time a python.
If I can create, I would like to Pull Request.

You can take a look at tinkertest to see how to write unit tests for Tinkerer, it's pretty easy. You run them using nose (just do pip install nose then run nosetests from tinkertest directory).

I have tried the pip install nose and nosetest.
I'm trying to make a test by reference to test_category.py.
But the test will be terminated in utils.is_module of test_category.py.

def setup(app):
    if utils.is_module(app):
        return
    app.connect("build-finished", build_finished)

Is there a better way run?

Let me take a look at this when I get some time. Setup shouldn't terminate your test.
