* Dynamic tabs: use buttons rather than links
- change docs
- add mention that tabs should be <button> elements
- tweak styles to neutralise border and background
* Update js unit and visual test accordingly
- replace links with buttons
- make one specific test that uses links instead of buttons, as we still want to support it despite it being non-semantically appropriate
- Leaving a couple of tests for now. The test for removed tabs should be redone so that tabs are removed programmatically (as the approach of having that close button inside the link is invalid and broken markup). The test for dropdowns should be removed together we actually ripping out the handling for dropdowns in the tab.js code (arguably a breaking change, though we discouraged this for a few versions and effectively "deprecated" it)
* Add isolation:isolate to prevent focus being overlapped

While technically it still works, we're already saying authors shouldn't do it later on, and we removed any examples of this. This was a straggler.

Replaces shorter examples with more sensible/representative/inforrmative text. For longer passages, resorted to using SFW extracts from http://katyperryipsum.com/
