Attachments not extracted if filename is getting too long.

[KirstenZa]

The script stops if filenames are getting too long during extraction (e.g. limits of NTFS file names). This happens pretty often for me when using the template:
%date%_%time%_%fromMail%_%subject%_%filename%

For "regular users" it is even hard to understand what and where the problem is, especially when trying to extract the attachments of hundreds of e-mails.

I tried a simple fix. It solves my problems right now.

"implementation.js" (line 70):

if (filename.length > MAX_LENGTH) {
    filename = filename.substring(0, MAX_LENGTH);
}
