Case problem with begin and end tags

[surruk51]

If the vcf file contains
begin:vcard
end:vcard

(e.g as exported by Thunderbird) instead of

BEGIN:VCARD
END:VCARD

it fails because it tries to split the file using:
$this -> RawData = explode( 'BEGIN:VCARD', $this -> RawData);

This can be fixed by changing line 132 of vcard.php to
$this -> RawData = preg_split('{^BEGIN:VCARD}miS', $this -> RawData);
