Fixed broken Selenium test

The problems was that visual editor is the default editor at
en.wikipedia.beta.wmflabs.org, and the test was expecting source editor.

The test now works also locally, using mediawiki-vagrant.

Removed headers from some files. We no longer use those headers.

Removed cucumber tags we no longer use, mostly internet explorer.

Added missing dependency (rake) to gemfile.

 Feature: Math
 
   Scenario: Display simple math
     Given I am logged in
-      And I am at page that does not exist
+      And I am creating a page with source editor
-    When I click link Create
+    When I type <math>3 + 2</math>
-      And I type <math>3 + 2</math>
       And I click Preview
     Then the page should contain an img tag
       And alt for that img should be 3 + 2
-      And src for that img should come from //upload
+      And src for that img should contain /math/
