Move entity cache from web.request.ConnectionCubicWebRequestBase to repoapi.ClientConnection ResultSet._build_entity relies on an entity cache to avoid going round in circles (stack overflow due to infinite recursion) e.g. in a postcreate script. Clear the cache at commit/rollback time to avoid unexpected side effects; and explicitly clear the cache in a few tests where we mix ORM and RQL using the same connection.

// This contains template-specific javascript

function filterLog(domid, thresholdLevel) {
    var logLevels = ["Debug", "Info", "Warning", "Error", "Fatal"]
    var action = "hide";
    for (var idx = 0; idx < logLevels.length; idx++){
        var level = logLevels[idx];
        if (level === thresholdLevel){
            action = "show";
        }
        $('#'+domid+' .log' + level)[action]();
    }
