Horde_Mime::decodeParam breaks when the MIME boundary contains an apostrophe.

The splitRegex (line 440 in Mime.php) seems to assume that apostrophes  
will enclose a string and not occur within it.  This means that the  
"boundary=" parameter is stripped out of the Content-Type header when  
it includes an apostrophe.

An example is attached.

The message body is OK, but since the boundary is missing from the  
Content-Type header it shows up blank in most mail clients.
