changed defaults for showSummary and showDetail

[Karel Zacek]

Hi all

I had problem to render <h:messages> after upgrading from myfaces-1.2.3 
to myfaces-1.2.4.
After little searching i stated that default values for showDetail and 
showSummary attributes of <h:messages> were changed.

1.2.3 - showSummary=true showDetail=false
1.2.4 - showSummary=false showDetail=true
