Cleaning leftovers from Eclipse

Eclipse generates some specific files and folders that may be removed from git in case any other person doesn't use Eclipse at all ([source](http://stackoverflow.com/questions/7186676/whats-in-an-eclipse-classpath-project-file)):

      .project
When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole 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.

      .classpath
classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

      .settings

Those files have been removed and .gitignore has been updated accordingly
