Remove unnecesary class (“modwin-main-content”) from the breadcumb of the “page to share” of documents and disseminations

Load presentations through Ajax (JS code was not being called) in the modal windows opened from the Resources page

windows will call to the code in main.js

Solves #9 (Show overlay during page initialization so that navigation menu for mobile is not visible, uncollapsed)

2) Integrate Rodolfo implementation of the Resources page (no need to use viewlet for the filters section because I removed a class from the theme/index.html that makes the main-container full width)
