Returns an array of mail parts from the current mail.

The array returned contains objects of classes:
- ezcMailText
- ezcMailFile
- ezcMailRfc822Digest
If the method is called with $includeDigests as true, then the returned
array will not contain ezcMailRfc822Digest objects, but instead the mail
parts inside the digests.
The parameter $filter can be used to restrict the returned mail parts,
eg. $filter = array( 'ezcMailFile' ) to return only file mail parts.

A typical use for this function is to get a list of attachments from a mail.
Example:
<code>
// $mail is an ezcMail object
$parts = $mail->fetchParts();
// after the above line is executed, $parts will contain an array of mail parts objects,
// for example one ezcMailText object ($parts[0]) and two ezcMailRfc822Digest objects ($parts[1] and $parts[2]).
// the ezcMailText object will be used to render the mail text, and the
// other two objects will be displayed as links ("view attachment")

// when user clicks on one of the two attachments, the parts of that attachment
// must be retrieved in order to render the attached digest:
$subparts = $parts[1]->mail->fetchParts();
// after the above line is executed, $subparts will contain an array of mail parts objects,
// for example one ezcMailText object and one ezcMailFile object
</code>
