Allow adding/removing multiple headers in one method call

[glassfishrobot]

It would be nice to have convenience methods to add and remove multiple headers in InternetHeaders and subsequently MimeMessage and MimeBodyPart.

These could include:

addHeader(Header header)
addHeadersWithHeaderList(List<Header> headers)
addHeadersWithStringList(List<String> headers)
setHeader(Header header)
removeHeader(Header header)
removeHeadersWithHeaderList(List<Header> headers)
removeHeadersWithStringList(List<String> headers)

@bshannon Commented This would be a change to the public JavaMail API, which normally requires going through the JCP. This will be considered for JavaMail 1.7.

I'm not sure addHeadersWithStringList(List<String> headers) makes any sense since there would be no header values.

Likewise, I'm not sure removeHeadersWithHeaderList(List<Header> headers) and removeHeader(Header header) makes any sense since the header values wouldn't be used, unless you expected it to match the header values as well. (Is there really a use case for that?)
