Add workshop recordings

[moneyinthesky]

We recently ran a series of workshops with the current ITP participants on:

• functions
• testing
• arrays
• objects

We also covered more general ideas such as:

• playing computer
• debugging
• problem solving techniques
• etc.

These sessions were all recorded and after recent discussions we were thinking it would be useful for other ITP participants - both current and future.
With that in mind, we could add recordings of these sessions into the curriculum.
