Basic user-configurable pointer image support.

GUI_POINTER_DEFAULT and GUI_POINTER_WAIT still use the Amiga system default pointers,
and will not be overridden by NetSurf.

Pointer imagery lives in Resources/Pointers and the filenames are all defined in the
ptrs array at the top of gui.c, in the same order as in gui_pointer_shape - with the
exception of GUI_POINTER_DEFAULT (this instead points to a "Blank" pointer for hiding
the pointer) and GUI_POINTER_WAIT (reserved for future use, currently points to "Wait"
but this will change).

The file format is very simple.  It is a text file containing 16 rows of 16
characters, with a newline or CR (or, in fact, any character as this is not checked)
terminating each row.  The seventeenth row indicates the pixel on which the "point" is
set, as two digit X direction, a space, then two digits for the Y direction.

Pointers/Point is based on the hand2 image by Andreas Kuerzinger (the original is in
the AKPointerz.lha archive on Aminet)
