signed requests for online maps

change the return value structure from getFeatures to return the entire json structure for each feature; this enables preservation of marker-symbol, color, coordinates, etc. when moving an existing marker

return folderId, if it exists, with each feature returned by getFeatures, to allow filtering by folder; modify setupSession to only return API version 1 if the API is version 1 AND the map ID is valid

add getFeatures to return a list of map features with IDs; move an existing marker by specifying existing marker ID in call to addMarker
