Need to be able to change working directory in a process

[stevengill]

Essentially, I think procstreams be able to do the following.

p('cd temp/repositories/')
    .and('git clone '+ android)
    .and('cd incubator-cordova-android')
        .and('git fetch --tags')

Right now it doesn't keep track of the working directory. We talked the other night about this. You were saying you were going to implement a process.chd into procstreams.

Thanks. I've already got ideas for this.
