New: capp_lint is installed with jake install

Previously we had to install capp_lint separately from Cappuccino.
Now capp_lint will be installed with Cappuccino.
Before capp_lint was installed in /urs/local/bin/, now it is in /usr/local/narwhal/bin/.
Merge pull request #2105 from Dogild/capp_lintInstall
