A Patch for Partially Blocked Plugin Messages in EVMSGUI

When starting EVMS engine, EVMSUI uses a "startup_window" 
to display status, like "Discovering segments". In the meantime, if 
a plugin sends back a question, EVMSGUI uses a message 
window to display the question and wait for responses. 

However, the message window is placed behind the startup window. 
And the message is partially blocked. Users cannot move the message
to the front.

The message does attempt to make itself on top of the main window, 
but the problem is that the main window doesn't exist yet. 

So I added code to make the message window a transient of the startup
window, if the main window is not there. This essentially puts the message
window at the very top. 


Created a patch for 2.5.5 and tested on my SLES10 box.
