GRADLE-3149
Adding support for the property 'configfailurepolicy' in useTestNG(). Added default behavior to test case.
Wrapper respects -q/--quiet options
Format decimal numbers in test checks with locale dependent decimal separator
Toggle for wrapping longer lines in 'code' blocks.

- Previously feature was developed in the #342.
- Summary:
  - If lines inside 'span.code pre' selector are longer then a screen width, it is very hard to read and interpret results properly.
    - At the bottom of the page check-box will appear, which enables/disables line wrapping.
    - Visually check-box is not distinctive from the footer, but is a part of it.
    - After toggling, it will wrap lines with small amount of CSS.
      - All CSS properties are supported by major browsers (included IE 8 and above).
        - Sources:
          - https://developer.mozilla.org/en-US/docs/Web/CSS/white-space
          - https://developer.mozilla.org/en-US/docs/Web/CSS/word-wrap
          - https://developer.mozilla.org/en-US/docs/Web/CSS/word-break
    - Feature was extensively tested on Firefox, IE (from 7 to 11), Google Chrome, Chromium and Opera.
      - Test were performed on Linux and Windows 7.
    - As agreed in #342 feature does not use any form of persistence.
