Add support for taking screenshots

[anuragc2001]

Describe the solution you'd like
Take screenshot of the whole desktop without letting the user know about it and save it in a different folder ready to be sent via Gmail API or upload it to the ftp server

Can this issue be assigned to me, please?

I have successfully taken a screenshot, the following features are left:

1. Organizing files in directories (Ongoing)
2. Sending those files via FTP / Mail
