Added addLocationListener() to the PHPManualView.java file. This will catch the links whey they are clicked on, and load the correct PHP Manual page.

Still need to catch the http:// links and direct them to either the default browser, or to ignore them.

This addresses ticket #379

Also may need to do something about when you click on a function and are navigating in the page, if you change focus the Manual will reset to the function that your cursor is active in.
