[NEW] oclint

[ryandesign (Ryan Carsten Schmidt)]

Thanks. Some observations:

• Since this project is hosted at github, it should use the github portgroup.
• If possible, fetch from a tarball instead of from the git repository. The github portgroup will do that by default (i.e. if you don't override fetch.type).
• Since this project builds using cmake, it should use the cmake portgroup.
• Instead of including a "cd" command in build.cmd, set build.dir.
• Instead of using "system" to run "cp -R", use the MacPorts "copy" command.
