[no] Antialiased lines in automap

OpenGL has the capability to do antialiased lines. Look at the following page for info (you will need to scroll down some):

Simply put, you need a glEnable(GL_LINE_SMOOTH); command.

Sadly that makes lines disappear quite frequently - and it looks somewhat strange so I won't do it.
