Update Eclipse formatter / style guide, add advanced_tutorials target

This updates the Eclipse formatter:
* Maximum line length doubled (now at 160)
* All function arguments are now wrapped and indented

Some re-ordering/re-naming has automatically been done by the Eclipse formatter exporter in the XML file. (I think we should let it as is; otherwise the XML edit would become very difficult).

I updated the style guide to specify how multi-arguments functions should be wrapped/indented, I think we should let the user free to decide how to wrap the arguments; it really depends on the function.

I also added an `advanced_tutorials` target in cmake.
