Mavenify client-side javascript/css libraries

 - Integrated the "webjars" versions of the ui dependencies
    => using all the latest versions of the libs (see properties in wildlife-web/pom.xml)
    => adapted the jasmine maven plugin to point to the libs located in the target folder, not in the sources anymore
 - Themified bootstrap with Bootswatch-united
    => exporting the Bootswatch-united as the bootstrap lib
    => currently not customizing any brand color of the theme, but it'll be handled by using lesscss:
        -> as the latest lesscss compiler has not been released yet (needed for Bootstrap 3.1.1), commented out the plugin lesscss-maven-plugin
 - Adapted app.js to new Angularjs version:
    => ngRoute is now outside the main angular.js library, need to declare angular-route.js dependency
    => need to use the ngRoute within the app.js
 - Adapted html/css classes to new Bootstrap 3.1.1
 - Added some fields in the Member form
