Move texts from xhtml/java into oxtrust_en.properties

[yurem]

oxTrust has full i18n support. It also allow to customize oxtrust_{xy}.properties via external resources. But in xhtml/java there are texts. We need to move all texts to oxtrust_en.properties.

Example for java:

    @Inject
    private FacesMessages facesMessages;

    facesMessages.add("#{msg['string.key]}");
    facesMessages.add(Severity severity, "#{msg['string.key]}") {
    facesMessages.add(String clientId, Severity severity, "#{msg['string.key]}") {
    facesMessages.add(Severity severity, "#{msg['string.key]}", Object ... params) {

Example for xhtml:

#{msg['string.key']}

More text has been move to properties files in other issues, plus the one moved in this issue.

Also moving text to properties file is a progressive task, we fix them ask we see them in code.
