* Fixed the log redraw which didn't happen as the display's scheduler

didn't get re-added to the task scheduler until a new event happened.

* Added redraw delay interval of 100ms, consider 50ms.

* Removed exceptions from core::DownloadStore::save.

* Added load, load_run, tied_stop and tied_remove to man-page.

* Cleaned up the command/option instances, move them to Control.

* PCB::load_up_chunk grabbed the errno from m_downChunk, not m_upChunk.

* Various string operations were moved to rak/string_manip.h.
