Clean code to manage multiselect jquery: All code is centralized
into function multipleselectarray (except loading of css). Code is prepared to choose which plugin to use (only a if is required to switch or add a new manager). Introduce working version with multiple-select jquery plugin. Removed deprecated old jquery plugin.
