[RFR] View title: Use template

[fzaninotto]

This PR deeply changes the way view titles are handled. Functions are not accepted anymore by View.title() - only strings. But, and "that is a big but", the string is interpreted as a template, and has access to the raw entry. That allows to customize the view title as follows:

post.editionView().title('Edit post "{{ entry.values.title }}"');

In addition, the default view titles are now better. For instance, for an Entity('posts'):

• creationView: "Create new post"
• editionView: "Edit post ng-admin 0.3.2 : label is undefined #123"
• deletionView: "Delete post ng-admin 0.3.2 : label is undefined #123"
• listView: "List posts"

I had to add inflection to handle singularization/pluralization. It's a good library, and I believe we will use it on other places (first, to remove default field label camel case).

I also chose to remove Entity.addMappedField(), and to add all non-mapped properties of the rawEntry from the response to the Entry by default. This removes a big WTF effect I had when trying to customize the deletionView title, and has no side effects.

Lastly, to allow the view title to support both a template and a default template, I updated the Compile directive to make it transclusive. This was a prerequisite for #118, so it goes in the right direction.

Closes #141.

I couldn't find another way to make the inflection object available to the ngInflection filters. I'm not satisfied with it, there must be a better solution. Ping @manuquentin.

You can maybe use the requirejs shim.exports to specify the global variable name. You should also mark inflection as a dependency of ngInflection in the requireJS configuration

I tried ; it doesn't work. Besides, the inflection lib seems to support RequireJS, so I don't understand.
