Link Selection Change

I changed the Linkage program so that a click anywhere within a link will select it. This is in addition to the already existing code that would detect a click anywhere within about 8 pixels of the edge of a link. That selection distance was also increased for solid links but due to a small oddity in the architecture of the software, selection of a solid link is not perfect and being close to the outside, while still inside the link, may not select the link. This is only by a few pixels on the screen so I think that no one will ever notice.
