Some images (plus, minus, bing) are not referenced properly for JAR use

[The111]

The loading and error images are reference as follows:

LOADING_IMAGE = ImageIO.read(JMapViewer.class.getResourceAsStream("images/hourglass.png"));
ERROR_IMAGE = ImageIO.read(JMapViewer.class.getResourceAsStream("images/error.png"));

This is a good thing, since if somebody uses the JMV release JAR file in an application, these images can still be found through the JMapViewer.class reference.

However, the plus, minus, and bing images are referenced as follows:

ImageIcon icon = new ImageIcon(getClass().getResource("images/plus.png"));

The problem with this is that if somebody uses the JMV release JAR in their application, and creates a subclass of JMV, that class will not be able to find the path "images/" if it has a different package. Thus it is probably smart to change these references to the same style as the earlier ones, like this:

ImageIcon icon = new ImageIcon(JMapViewer.class.getResource("images/plus.png"));
