Javascript coding style indent 2

    In order to improve the javascript coding style an indentation of
two spaces must be used in the whole project.
    A jshint option has been added, and all the files which violate
this rule have been corrected.
    In addition, some code style corrections have been made.

Implements: blueprint jshint-codestyle
