allow getTrips() and getMessages() with limit directly from Query instance

[stklcode]

Issue

Querying trips and messages with result limit, like the following example from the README.md is not supported when using filters:

List<Trip> trips = ura.forStops("100000")
                      .forLines("25", "35")
                      .forDirection(1)
                      .getTrips(10);

Actually the unfiltered method works:

List<Trip> trips = ura.getTrips(10);

There is also a workaround for the first example:

Query query = ura.forStops("100000")
                  .forLines("25", "35")
                  .forDirection(1);
List<Trip> trips = ura.getTrips(query, 10);

The wrapper to call it directly from the Query instance is missing though.

Same for getMessages().

Solution

Add both convenience wrappers to the implementation.
