docs: updates to the documentation to support new markdown renderer (#3672)

Companion PR for karma-runner/karma-runner.github.com#62.

* docs: fix invalid heading syntax

It is not recognized as a heading by the markdown parser without a whitespace.

* docs: fix weird syntax to reduce diff

Old parser considered this the same list, but new parser assumes that these are two separate lists. Technically it should be a nested list, but it is old and shouldn't really matter. I'm doing this change to reduce the diff I need to review after switching to the new markdown parser.

* docs: fix invalid markdown

Items nested in the list item, must be indented 3 spaces, not 2 spaces. New parser produced a pretty messed up markup from the invalid markdown.

* docs: remove redundant whitespaces in the list items

 To execute javascript unit and integration tests with ember.js follow the steps below:
 
 1. [install karma]
 
 2. install the qunit plugin

 4. generate a configuration file for karma
-  ```bash
-  karma init
-  ```
-  note -the above will walk you through the basic setup. An example configuration file that works with ember.js/qunit and phantomjs is below

-  ```javascript

-    config.set({
-      basePath: 'js',
-
-      files: [

+   ```javascript
+   test('one should equal one', function() {
