20 - removed folder trunk/bench.
- added ISE13.1 complete project, with synthesis, map, place & route and timing reports. This project generates bitgen file to program a Digilent Atlys board to verify the cores in FPGA hardware, and include a simulation testbench to simulate the cores.

13 spi_slave.vhd: v2.02.0120
spi_master.vhd: v1.15.0135

Several bugs fixed. Master and Slave cores tested at all spi modes, at 50MHz SCK, including continuous transfers.

12 SPI_SLAVE: v2.00.0110 [JD] FIX: CPHA bugs:
-- - redesigned core clocking to address all CPOL and CPHA configurations.
-- - added CHANGE_EDGE to the FSM register transfer logic, to have MISO change at opposite
-- clock phases from SHIFT_EDGE.
-- Removed global signal setting at the FSM, implementing exhaustive explicit signal attributions
-- for each state, to avoid reported inference problems in some synthesis engines.
-- Streamlined port names and indentation blocks.
