Add Matlab File (.mat) support

[Lee]

I am a researcher in Computer Science and much of my time is spent on browsing .mat files (some datasets) downloaded from the Internet. From my perspective, browsing the inner data in .mat files is as important as browing xml files, readme files and so on.
This feature would be helpful because the default way to read a .mat file is opening Matlab, which is a heavy software and takes a lot of time.

As far as I know, there is a feasible and rather convinent way to browse the data in .mat file via using mat4py module in python.

$ python -ic "import sys; import mat4py; data = mat4py.loadmat(sys.argv[1]);" example.mat

But I am not familiar with how to implement such a similar function in QuickLook.
