[RFC][icedtea-web] Fix NumberFormatException in PluginParameters

[Thomas Meyer]

Hi,

Maybe introduced by changeset 741a105054af (Remove redundant HTML-tag
scanner from ITW. Do not reconstruct tags.)

Handling message: GetJavaObject instance 3 Worker #1/IsPriority=false/IsFree=false/Message=instance 3 reference -161 GetJavaObject
Exception in thread "NetXPanel initializer" java.lang.NumberFormatException: For input string: "4294967295"
	at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
	at java.lang.Integer.parseInt(Integer.java:495)
	at java.lang.Integer.valueOf(Integer.java:582)
	at net.sourceforge.jnlp.PluginParameters.getWidth(PluginParameters.java:154)
	at sun.applet.PluginAppletPanelFactory$2.run(PluginAppletPanelFactory.java:104)
	at java.lang.Thread.run(Thread.java:722)

Proposed fix:
