[Global/Eclipse] add ".project" file

[jskelin]

ignore project description file

Reasons for making this change:

Ignore generated file by eclipse .

Links to documentation supporting these rule changes:

If this is a new template:

• Link to application or project’s homepage: TODO

@jskelin actually, this comment from the link makes me curious:

The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.

This to me feels like it has value, and might be useful to have in version control, even if it's generated. Can you elaborate on why it's safe to exclude this from version control?

Looks like @jskelin does not have this project forked anymore. I think it would still be beneficial to at least address the .project file in the template. I have opened my own Pull Request #3305 to make it opt-in to ignore. Could this possibly be extended to .cproject already ignored or perhaps .classpath/.settings?

A few other templates have the .project file listed, but should be consolidated to the Eclipse .gitignore.

@larry1186 thanks for submitting #3305 - I'm going to close this out as it's now unnecessary
