Offline dependencies

These 3 depenencies I have not been able to locate in the online Maven repos, i.e. search.maven.org. They have to be included locally as jars. It would be nice to move these to online ones as well.

compile files('NuBot/lib/nubot-dependancies/mail.jar') compile files('NuBot/lib/nubot-dependancies/org-netbeans-modules-java-j2seproject-copylibstask.jar') compile files('NuBot/lib/nubot-dependancies/org.json-20120521.jar')
