Minor Tutorial corrections

[Innocence]

Two tutorial paragraphs which should be looked into:

Loading and Unloading Units

Now, select one of the units inside the transport.

Right click on the yellow waypoint.

Then, while holding down CTRL (so that the next order will be appended to the existing list of orders), right click on the land. Once the tranport arrives there, this will give the unit orders to disembark at the waypoint and move somewhere on the island.

Should probably add that it's not strictly necessary to click the waypoint to disembark, you can click any land area near the waypoint

Foreign Relations and Messages

To send a trade offer, press the 'Send Message' button, and then press the 'Add Trade Agreement' button on the bottom of the Message window.

There is no such button in the Message (anymore?). Theres a separate Trade icon on the info bar
