Missing or unusable simconnect causes hard crash

[spiliot]

A user with a corrupted installation of simconnect reported a hard crash of jeehellrmp after clicking any button. The program starts but no connection is established with FS and after any click windows reports the program stopped responding.

This is due to the fact that no error checking against a missing or unusable simconnect is being performed in the code. For coding simplicity we just assume simconnect is there and working. While this can be fixed, it is of low priority.
