New blog post on why all scientsts should attend a bootcamp

@gvwilson or @amyrbrown: What do you think about this as an idea for a blog post? I can't `make check` on my machine, so apologies if there are any html errors. I'm happy for you to decide on the time and date (which is why I've left those fields blank). 

@gvwilson You'll recognise some of this content from your 05-open.md git lesson. I'm not planning on giving that lesson at the UniMelb bootcamp (because I know nothing about copyright and access issues), which is why I've used some of the content from it in a sort of closing address instead.
