Fixing importing doc

Fixed some details about the importing links and documents.

- Added extra info to Bitbucket importing
- Organized docs in alphabetical order
- Moved Importing link to general documentation, instead of workflow (that's where Sytse asked me to add it)

Added line about adding docs in alphabetical order

I believe it's important to be organized when adding documentation, so whenever it applies, I believe documents should be added in alphabetical order.

There is no need to check if `repository_ref` is present as:
```
      @repository_ref = if repository_ref.present?
                          repository_ref
                        else
                          nil
                        end
```

is as same as doing:

```
@repository_ref = repository_ref
```
