Changes back-ported from rspec3 branch

This is just breaking up the large `road-to-rspec-3` branch a bit. Each of these commits have been cherry-picked and would be good to have in place before the upgrade.

See merge request !792

update fog to 1.25.0 and add multipart upload support

This merge will fix backup uploading problems to s3, closing gitlab-org/gitlab-ce#1059

fixed links

@job I am trying to fix these links, since they work on the commit, but then they didn't work on the website when the commit was merged.

I tried changing them here, but I'm not sure if they'll work when merged. I tried to use localhost to test this, but it only works with www-gitlab-com

Thanks!

Update browser gem to version 0.8.0

Internet Explorer 11.0.9600.17633 has a new User-Agent string (tested using [BrowserStack](https://www.browserstack.com)):

```
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
```

This is supported in v0.8.0 of the browser gem:

They're called constants for a reason, after all.

This might see a minor speedup in test cases that call this method many
times.

As of Ruby 1.9, this is the correct way to handle `respond_to?` for
methods implemented by `method_missing`.

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)

Thank you @job for merging previous changes.

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.
