Replaced the gpio_defaults_block_0000.mag layout with gpio_defaults_block.mag 

so that it contains a valid layout after processing by Openlane (since the
verilog module is named gpio_defaults_block).  Corrected the orientation of
the defaults block layouts on the right side of Caravel and erased the
incorrect routing there.  Reinstated the copyright, user ID text, open source
logo, and Caravel logo.  Revised the gen_gpio_defaults.py script to handle
the first five GPIOs in the same way as the others, although as fixed entries
which cannot be modified by the user project designer.
