       Installs the Allegro mouse handler. You must do this before using any
       other mouse functions.

RREETTUURRNN VVAALLUUEE
       Returns -1 on failure, zero if the mouse handler is already installed
       (in which case this function does nothing) and the number of buttons on
       the mouse if the mouse handler has successfully been installed (ie.
       this is the first time a handler is installed or you have removed the
       previous one).

       Note that the number of mouse buttons returned by this function is more
       an indication than a physical reality. With most devices there is no
       way of telling how many buttons there are, and any user can override
       the number of mouse buttons returned by this function with a custom
       configuration file and the variable num_buttons. Even if this value is
       overridden by the user, the global mouse variables will still report
       whatever the hardware is sending.
