[gui][PATCH] AWTEvent.toString fix

[Thomas Fitzsimmons]

Hi,

This patch fixes AWTEvent's toString method to print the event source's
name, rather than its value.  This change eliminates a deadlock when
printing events from within EventQueue's postEvent method.  It also
makes our event output more like Sun's.

postEvent is called from the peers while the GDK global lock is held. 
Some Components, from their toString methods, call peer methods that
attempt to obtain the GDK global lock.  When an attempt is made to print
one of those Components, the result is a deadlock, since
gdk_threads_enter is not reentrant.

Patch committed to the java-gui-branch.

Tom
