Implement CECP 'computer' command

Remember if the 'computer' command was received from the GUI, and use
this info when setting the UCI_Opponent option to distinguish 'human'
and 'computer' as first word, instead of the uniformative 'none'.
The implemntation assumes 'computer' would be sent before 'name', which
XBoard does (but the CECP specs do not guarantee).
