Update to graphics

The pictures used for some skills have been changed and more are to come according to this announcement:

We have updated some game visuals. The fishing, mining and the jail image have been improved, furthermore we've added two new images: sailing and farming.

We've seen discussions about the server performance and images like these: Some players were worried about the server performance related to the images. Rest assured that these images merely have any effect on the game's speed (Only dial-up users might want to switch the images off at the options page).

We expect to have updated/added the last 10 images in +/- 3 weeks (Cooking, smithing, smelting, constructing, school: trading, school: constructing, moving-islands, moving-caves, lock picking).
