All words in human friendly URLs should be capitalized when rendered

Thanks to the work done in issue ORG-81 and related issues, documents can be accessed by their case-insensitive wiki name. Ignoring case is the proper thing to do when interpreting a human friendly URL so that it is not fidgety.

However, when a wiki link to a page is generated from the document name, all the words should be capitalized before the non-alphanum characters are removed.

For example, given a document titled "How is Arquillian pronounced", I would expect the link to be generated as:

http://community.jboss.org/wiki/Howisarquillianpronounced

Instead, the plugin produces:

http://community.jboss.org/wiki/HowIsArquillianPronounced

I find the second link to be much more readable than the first, and it fits more in the spirit of wiki links. Both of these links are functional, so this is just a style issue, but an important one.
