Doesn't look in ~/Documents/Arduino on Mac for 3rd party boards

I'm transitioning from using the Arduino IDE to using ino to manage my build & upload process. I have some 3rd party board defintions from SparkFun and others in ~/Documents/Arduino which is the Arduino IDE's preferred location for such files but ino doesn't look in this path. I have a fix working in my environment so I will be sending a pull request over soon.

For the moment there is still an issue where it looks for the cores directory in the same dir as the boards.txt file. For now I've just created a symlink to the standard arduino cores dir. I'm still trying to understand the code well enough to code up a fix for it.

Ditto - just created a symlink to work around the problem.
