[7u10] Review request for 7194469 Pressing the Enter key results in an alert tone beep when focus is TextField

[Alexander Scherbatiy]

This is the same fix backported from the JDK 8 to JDK 7u10 without changes:
bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7194469
webrev: http://cr.openjdk.java.net/~alexsch/7194469/webrev.01/

The TextField control starts beeping on some keys pressing (enter, up, 
down...) after switching the EDIT control to RICHEDIT.

The fix disables and enables the beeper by SystemParametersInfo method 
with the zero value in the fWinIni param for the RICHEDIT control if 
requested keys are pressed.


Thanks,
Alexandr.
