FMSec 4.0 released!

Added suport for Thunar from Xfce 4.x (without TrueCrypt, which not only is deprecated in general, but also doesn't compile with newer compilers any longer).
Unfortunately, no suitable MimeType values could be found and "application/octet-stream" is taken strictly by Thunar, allowing the operations to be done only on files of unknown type, while you'd wand to encrypt e.g. also text files. A workaround is to skip the limitation, but this causes some of the operations to appear in the context menu of all objects, even unsuitable ones.
