Fixes and new scripts.

Batchaday is now completely fixed, there were some errors with
parentheses placement at first. Command.bat is also fixed of its old
problem, but it displays a one-time syntax error before allowing you to
continue. Fakehack is a new and improved fakedelete script, though I
left the older, simpler fakedelete in.  Try the random number game, it's
really fun!
