Description

methods like setDBProperty and getDBProperty work slow, if are used several times one after another. Example:

var a = this.getDBProperty('a');
var b = this.getDBProperty('b');
var c = this.getDBProperty('c');

Each getDBProperty-call does localStorage.getObject which may be slow if readable object is too big (it may take 100-150 ms). So, it's better to read list of values with one call, like:

this.getDBProperties(['a', 'b', 'c']);

And same for setDBProperties.
