Integrate tour generator 'webhook' into galaxy.

[hexylena]

One of the first things I do when I setup a galaxy, just to test that dependencies work properly, is run a BWA job. Finding the 2-3 datasets I need for that is always a mild annoyance.

EU has a fantastic plugin for this, that gives users a one-click experience to pull in data and run the tool. I love this feature, it completely simplifies my testing as an admin.

I feel like everyone should get this experience by default since it's such a useful utility for having some example data to try out.

If possible it would be great to consider integrating this into the core codebase:

maybe someone from eu like @davelopez would be able to help here
