Add OS-specific files to .gitignore

[ghost]

I think that the default .gitignore file DrWatson generates should include the following OS-specific patterns:

.DS_Store
.DS_Store?
._*
.Spotlight-V100
.Trashes
ehthumbs.db
Thumbs.db

Also, ignore .ipynb_checkpoints for Jupyter Notebooks.

Also, in case somebody wants to use Documenter.jl, it should ignore docs/build

If you want to make a PR you can edit this file:

yeah a pr would make you a contributor, which is cool!!!

At the moment, my company does not have a policy on open-source contributions, but management is looking into it. For now I don't want to patch something and risk it turning into an intellectual property dispute, causing problems for everyone.

I was thinking we could do OS specific editing of the gitignore file at build as well, for MacOS especially.

I think the complexity and first-run-time penalty of adding a build stage is not really worth it. There is almost zero drawback in adding the OS specific files for all users given that most of them start with .

[Datseris]

But maybe I am wrong!

I think it would be simplest to just hardcode all of the known OS-specific filenames into the gitignore file. That way it doesn't matter who checks it out on what or if they migrate to a new system.

@cherbigmet, @Datseris: I took it a step too far, completely reworked the gitignore file...you can see the changes in the PR #58. I took a lot of data from gitignore.io, and mentioned it at the bottom of the file.

Wow! Well, if it passes, then it definitely takes care of my concerns, at which point, feel free to close this ticket.
