[rfc][icedtea-web] alowing bom character in basic parser

[Jiri Vanek]

Thsi is fix for
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=2690

In bugI stated that no direct action will be taken, but then I realised that yes, tagsoup is 
removeing this for us, but maybe it is doing it wrongly - as the character is mandatory for utf 16 
and 32

So I think its a bit better to add it to switches in parser.

I hope I had refactored all the scanWhitespaces corresctly.
