insert local SQLite populating for autocomplete

 * add new way to retrieve data for the widget
 *  dataSourceType: 'remote' - standard mode via http request defined in dataSource
 *                  'local'  - sqlite mode. Retrieve data from database alias defined in dbName (new param) and SQL in dataSource

This is not the best solution.. .but it's a start to create something works locally on SQLite database

Just wait... I have some problem with selectSuggestions method
