update .gitignore

[bjlittle]

This pull-request updates the .gitignore base on https://github.com/github/gitignore.

Is this perhaps something we should be covering in our templating solution?

[pp-mo]

I do think this is all good, and in comparison with the existing includes all that currently covers 👍

It's also very close to github/gitignore/Python.gitignore
So the templating idea does seem a really good one.

Given the existence of a very usable template elsewhere = https://github.com/github/gitignore as suggested,
do we want to

• (1) reference that directly in our templating actions, or
• (2) make an scitools-specific snapshot copy of that, and maybe ..
  • (2a) .. template that (standard scitools version) against the latest in github/gitignore ?

[pp-mo]

Ok from offline conversation with @trexfeathers , the templating approach does have value, but we will consider that separately + elsewhere (in Scitools/.github) SciTools/.github#25

Merging even though the iris-source tests fail : #463 or similar will eventually fix
