porting test cases from html to bbcode

this step is needed to carefully check every buyg we could left.
Fix tests, set old defaults

The tests in /test/tests folder are needed for the markdown/gfm compatibility.
In order to test the old behaviour (and be sure we didn't f**k up), other standard values were needed.
modify /test/index.js in order to make it possible to test different testcase folders
fixed wrong behaviour

now all test cases will be added, and not destroyed when checking a new folder
remove the old tests (and test webpage) from the repository

the tests will be edited to be run by node
Modified <autolinks> in original tests

An autolink is supposed to generate `[url]href[/url]`, as there is no description (text). Obviously, it's philosophy.
Autolink now generate [url]href[/url] (and not escaping when nerdzing)

* Autolinks
As they have no description, an [url]href[/url] is ok.

* Escaping
We don't need no escaping: it's done by nerdz backend code, we have to give it a bbcode text, a text even a man could write. And a man does _not_ write &quot; :D
update test/index.js: Nerdz tests are now in /test/nerdz folder
NERDZ TESTS!

finally, nerdz tests are beginning! things must be fixed, but they're a good starting point.

* add tests in /test/nerdz (already updated /test/index.js)
* remove old html/js test system with qunit.js (moving to the node.js system)
merge the actual readme
temporary deletion of cenci0's modifications (breaking tests)
Reintegrate cenci0 modifications. now fixed.

A silently merged change broke it all, spent two days looking at diff
files.
add socialmedia tests
cleaned a bit
