Upgrade maven-site-plugin to fix error when using Maven 3.1.0
Merge pull request #135 from anserran/master

Added 'useDoubleNumbers' configuration parameter
Reverse polarity of useDoubleNumbers test to prove property changes the default
Remove unused import
Remove ignoreSnapshots, we no longer use snapshot of Commons JCI
Rename setAdditionalProperties to setAdditionalProperty

Avoid confusing naive introspectors (such as MuleSoft's DevKit) by
ensuring the set method for additional property values is not named in a
way that makes it appear to be a JavaBean-style setter for the entire
map.
