Euroscipy update

I went through the notebooks I wanted to show at euroscipy and made some update.
like remove %pylab , speak of raw_input, %debug, GFM. 

Plus new notebooks on nbconvert from command line and custom templates example.

Still mostly in progress.

@MinRK what parts do you want to do, or do you want to present something specific ? 
Want to open a shared document with which part/which timing ?
