[RFC][icedtea-web] Fix usage of == -> .equals for various String comparisons

[Adam Domurad]

Hey, first try at a commit. 

I went through the source of IcedTeaWeb with FindBugs and went over all reported cases of == being used to compare String's. Some usage cases were valid (eg, .equals eventually called, magic String value). I noted one such usage case. The others were changed to .equals calls.

Changelog entry:
2012-05-15  Adam Domurad  <adomurad at redhat.com>

	Fixed uses of == to compare String objects to .equals where appropriate
	noted a non-obvious use of == to compare a 'magic' String reference.
	* netx/net/sourceforge/jnlp/JNLPFile.java: and
	* plugin/icedteanp/java/sun/applet/GetMemberPluginCallRequest.java: and
	* plugin/icedteanp/java/sun/applet/PluginCallRequestFactory.java:
	changed calls that compare String contents from == to .equals
	* netx/net/sourceforge/jnlp/Version.java: added comment explaining why
	== was used vs .equals
