Massage wording a little

Following @igalic's advice in issue #26, I've changed some of the wording to make it more friendly.
Massage wording a little

Removed trailing character that mysteriously appeared in line #13.
Rename "need help" to "support"

I also made the notice re: compatibility breakage a little more obvious. :)

Templates require that the module path be included in the declaration.

Adds name to centos repo

Without the descr, yum will throw a harmless error every time you try and install software

    Repository 'logstash' is missing name in configuration, using id

Note: It seems counter intuitive, but puppet yumrepo uses 'descr' to set the 'name', where as 'name' does nothing.
