BUG FIX Wishbone master ping mistake

Wow! Wishbone master didn't de-assert master_ready when a ping occurs.
Granted the ping happens so fast that it doesn't really matter if it
goes down in most situations but this should have gon down every time
there is a command sent to the master.

This might explain why Dionysus doesn't respond sometimes
MODIFY Changed wb_bram to work with 32-bit addr

Similar to the Wishbone SDRAM controller the wb_bram is now only
addressable in a 32-bit address space
SUPERFITIAL CHANGE: Removed whitespaces
SUPERFICIAL CHANGES White space removal
INITIAL COMMIT wb_mem_2_ppfifo

A module that can be used within slaves to control reading from memory
and putting the data into a local (much easier to use Ping Pong FIFO)

Read the readme.txt to see how to use this
DOCUMENTATION: Added a better description

Also added a better description of examples of the module
