Make bwoken more configurable and resilient to spaces

[alecgorge]

This PR adds two new configuration options to bwoken test:

--product-name          Specify a custom product name (e.g. --product-name="My Product"). Default is the name of of the xcodeproj file
--integration-path      Specify a custom directory to store your test scripts in (e.g. --integration-path=uiautomation/path/dir). Note that this folder still expects the same directory structure as the one create by `bwoken init`.

One new configuration option is added to bwoken init: --integration-path.

These options are important for large existing projects where the product name is different than the workspace name and where a folder called integration already exists.

This PR also allows bwoken to work even when there are spaces in the project path.

I noticed that Travis is now failing. I will fix this.

@alecgorge Thanks for writing this up! I've got some suggestions/modifications that I'll provide in the next day or so.

When is this going to get accepted? I ran into the same exact issue and was going to fork this repo to make the same exact change until I saw this.

Apparently, bwoken is using an older version of my script. You might want to look into the latest version that I've concocted here:
