Localization placeholders and small fixes

* Implemented placeholders for `formatMoney` and `formatDate` localization helpers.
* Removed `jquery` warning in `i18next`.
* ModuleManager now builds full component paths.

The first change addresses #205, it'll allow us to start "using" the currency and date formatting with a very basic implementation, and update to the right way when we get around to do #198 and #199, as part of the beta.

The second change is very minor and has already been done as part of the upcoming PR related to #176, but it was so simple and annoying in the console that I decided to give it as a freebie here, enjoy. :wink: 

In related fashion, the last change is to prepare for the coming PR related to #176, it ensures that `module.core` can be updated to the new component ownership and structure without breaking other modules, while still allowing them to migrate to the new approach.

Usage example

```javascript
var language = require("language");
var __ = language.__;
var formatDate = language.formatDate;
var formatMoney = language.formatMoney;
```

And in your render:

```
L’adhésion {__("example::costs")} {formatMoney(10)} et est disponible à partir du {formatDate(new Date())}.
```
