Need to properly concat lang strings for webservices

[Robert Lyon]

Currently there are places where the text displayed to screen is in the format of:

$html = get_string('stringidentifier') . $variable;

and

$string['stringidentifier'] = 'Example: ';

But that can lead to problems with translations so they need to be:

$html = get_string('stringidentifier', 'section', $variable);

and

$string['stringidentifier'] = 'Example: %s';
