Added function to set working directory.

If a working directory is set with wdir(), bashrc will cd into the
path stored in a file written in /tmp. A new terminal will then
have a shell in that directory.

cwdir() deletes the file in /tmp and pwdir() prints the working
directory from said file if it exists.
