Fix non breaking space (MODULES-3503)

[Jeoffreybauvin]

Hi,
There is a non breaking space in the file templates/mod/remoteip.conf.erb :

jeo@brs:~/dev/tmp/puppetlabs-apache/templates/mod$ cat -A remoteip.conf.erb 
..
# Declare client intranet IP addresses trusted to present$
#M-BM- the RemoteIPHeader value$
..

This breaks Puppet runs :

root@monserver /data/sites/web-all-share-01/htdocs/data # puppet agent -t --no-noop
