Some comments about feature tests

[fzalila]

Some comments:

1. __tests__:
   1. some helpers defined in the test scripts do not seem to be used (ex loadUrl, waitForText, ...), are they necessary?
   2. nt4s url needs to be removed, this should preferably be a config variable somewhere (lib/config.js baseUrl?), you can use http://test.fadi.cetic.be as a placeholder.
   3. if possible, use the test case identifier in the filename instead of introducting a new numerotation
2. provide examples in README.md
3. Test-scripts-specifications.md :
   1. links should be relative, not absolute
   2. some links are missing
4. Cockburns-specifications.md :
   • some links are missing
5. remove remaining pgadmin references

@banzo
For 1.i the identified helpers can be used in other tests. So they are necessary.
d2b241e and 4586b93 resolve 1.ii and 2.
For 1.iii, yes it is possible but after resolving 3., 4. and 5.

@SellamiRami
can you please resolve 3., 4. and 5. issues.

@banzo I resolved the issues number 3, 4 and 5.
In addition, I added the cockburn TC-6 and the test script TS-6 in order to consider the creation of a table using Adminer.
I think that everything is OK now.
