Subject: [PATCH] Portability

Manually include unistd.h in a couple of places get things building with gcc
4.7, which removed it from the global namespace. This fixes the following build
errors:

    src/A3.cpp:283:3: error: 'STDIN_FILENO' was not declared in this scope
    src/commands/CmdEdit.cpp:598:30: error: 'getpid' was not declared in this scope
    src/commands/CmdEdit.cpp:603:47: error: 'chdir' was not declared in this scope
