Build 2537 released: Serialization in Rebex Mail now actually works!

Due to a missing attributes in one of the internal classes of the MIME component, serialization of MIME classes was often impossible. This also affected ImapMessageCollection and Pop3MessageCollection. The build fixes this issue. Additionally, some minor FTP exception we discovered few days ago have been corrected.

Detailed list of changes:

• Mail (MIME): Fixed a bug that often made serialization impossible. This also affected serialization of ImapMessageCollection and Pop3MessageCollection.
• FTP: Fixed bad ArgumentExceptions in Ftp.Connect and FtpList.GetFiles methods.
