RFR (XS): 6359971:Threads tab: Simple text to explain that one can click on a thread to get stack trace

[Erik Gahlin]

Please review a small change.

Description:
UE feedback: The Threads list in jconsole doesn't have one thread 
selected by default. Selecting one thread (e.g. the first thread) by 
default is confusing. The first thread is not necessarily very 
interesting to look at.

Solution:
Write short message telling user that no thread has been selected.

Testing:
Verified that text is displayed in Threads tab.

A sponsor is needed.

Thanks
