uml lifeline

[Mike Power <mpower pit recurse net>]

First off I would like to praise you on an excellent application.  I use 
it a lot.

Second I would like to see if a small change could be made to enhance 
the app just a little.  In uml there is a shape called a lifeline.  A 
good little thing with one exception.  Its endpoints do not stick to 
stuff.  I have attached an example dia(ungzip'd) file.  This file 
contains two examples.  Where the end point of a lifeline does not stick 
to a Text object and where the end points of two lifelines do not stick 
to each other.  It would be great if they did actually stick to each other.
