Store Eclipse project settings in source tree

[tfmorris]

The source tree used to have Eclipse project files in at, but they appear to have been removed at some point.

In my experience, it's best to not only keep the .project & classpath files with the project, but also enable project-specific settings for things like Java code formatting, compiler warnings, etc. This ensures that everyone uses the same settings for the project and promotes code consistency. Without this, each developer's Eclipse-wide settings are used, causing formatting to vary from developer to developer. Even if the conventions chosen are the (current) Eclipse defaults, having them specified in the project settings keeps them from being overridden by a developer who has changed the defaults.
