new formula: tomcat-native 1.1.7

**Mountain Lion user: Before installing this formula you have to `brew tap homebrew/dupes'. This is needed, because on  the formula installs apr from homebrew dupes instead of using the one from OS X, which has broken links on Mountain Lion.**

This pull request will add a new formula for [Apache Tomcat Native](http://tomcat.apache.org/native-doc/).

ToDo:
* [ ] fix error, when installing with OS X's apr (installing with apr from dupes works fine) on Mountain Lion
