ftps (ftp over SSL) or better an option field in configuration of the ftp-plugin

[struckma]

Dear developers, thank you for your great fuse GUI! I have a proposal for an improvement: I would really appreciate an option for activating the ftps options of curlftpfs_static_mg (i.e. ssl, ssl_control, ssl_try, ..., tlsv1 and sslv3). Alternatively, a text input field to extend the curlftpfs_static_mg command line by some arbitrary options in general would help, maybe as advanced option. I would be happy (and I think, since I found a corresponding issue on the old google code tracker, maybe I am not the only one), if you could consider implementing this improvement. Thank you for reading my request. Stephan
