added into the repository: src/threadcontroller.cpp 

this file was out of controll by subversion (I forgot to add it)

added: the update can only download files from urles which begin with:
 http://downloads.sourceforge.net/
 ftp://ttmath.org/
this is in the case of someone hacked the server with *.ini file
