This commit introduces a new Scientist alternate role, Research Botanist

The additions here are pretty simple, but I'll support the job with
updates in the future. This commit only adds a headset, key, and starting
equipment. Plus the title itself.
This should be if(H.mind.role_alt_title == "Research Botanist").

What you're asking in this if is "Does 'Research Botanist' have a non-null value?", which it always will do, since it's just a string you've given the if.
