NB7.2 HR Fix: #214374 - Font in searchpanel has not anti aliasing

Description:
http://netbeans.org/bugzilla/show_bug.cgi?id=214374

Text in "Find" field in search bar (and in other places with editor's 
kit implementations like Create Watch etc.) was not antialiased.

Impact assessment: since search bar is frequently used this was a highly 
visible problem (regression).

Risk assessment: low. The fix only restores proper setting of 
renderingHints variable.

The fix has been reviewed by Milutin Kristofic and it should be verified 
by QE.
