Added overflow protection for the task buffer by increasing its size by a factor of 256. Size of 2^12 -> 2^20
Added maximum file size check during the writing process. This is to ensure that evil peers do not download large files which take up all of the system's harddrive space. The program issues a warning.
Minor changes to error message.
