* Fixed a buffer overflow when writting to the output buffer. This

would in some rare occasions cause memory to be corrupted. leading to
a crash.

* Added option for setting the http proxy and proccess's umask.

* Save the total uploaded for downloads between sessions.

* Moved from sigc++ to my own lightweight slot class for the task
scheduler. This saves some 5-600kb when compiled with debugging
symbols, 1-200kb without.
