Renaming RoseNMS

Today I have pushed all (or hopefully all) the required differences in the source files to change the name of the project.  Originally it was called Rosenberg NMS, named after a lizard or heath monitor that lives in this parts.  The name was cute but cumbersome.

I’ve cut it down now to just RoseNMS with no space in between. This will also fix the nightmare of using a space, hyphen or underscore in various pieces of the code. All three were used but with no space in between, there is no confusion.

The site URL remains the same at https://rmns.org/ however the read-the-docs url has changed to fit with the new name: https://rosenms.readthedocs.org/
