Added refresh button for UI
    
    Web UI is caching records. Currently only possible ways how to display updated record which was changed elsewhere - ie. in CLI are:
     * refresh page in browser (takes really long on slow vpns)
     * search facet: change filter, find, change filter back, find
     * entity details: go to search, select other entry, go back to search, select original entry
     * association facet: same as entity details
    
    These are unconvenient methods.
    
    This patch adds Refresh button to search, details and association facet. This button executes facets refresh method.
