Corrected inconsistency with module and controller parameters

There is an inconsistency when module and controller parameters are used with small leading characters. These commands don't work:
    
    zf.php create module event
    zf.php create controller index event
    zf.php create action show index event

These commands do work:
    
    zf.php create module Event
    zf.php create controller Index Event
    zf.php create action show Index Event

This patch corrects this inconsistency, so both ways work and even a mixture does.
