Fixed a bug in appobserver. When App not running no new timestamp was set and emails where send as often as the appobserver Thread checks for them
Added many more email messages
Threads can stop themselves
sendmail method gets a boolean now to determine whether or not to collect data
Initial check in main.cpp if config file is ok
ipcNamedPipe while loop no longer blocks on opening the named pipe. We will use this loop to write an general status mail message with a configurable timeout
If errno == 11 (EAGAIN) when reading from fifo try reading again.
