New: Console Mode editions of BBC BASIC

[Soruk]

Richard has updated the Console Mode editions of BBC BASIC to version 0.41. The changes in this version are:

• Added support for serial I/O, for example the EXT# function returns the number of characters waiting in the input buffer.
• Added a new example program animal.bbc which is the famous 'guess the animal' program, which learns from its mistakes (sort of).

Version 0.41 may be downloaded from the usual place.
