Upgrade to L5 + huge refactor + more. closes #2

New stuff:
- Signup + email confirmation.
- Updated authentication strategy with remember cookies. closes #5
- New search system with some example gambits! This is cool - check out
the source. Fulltext drivers will be implemented as decorators
overriding the EloquentPostRepository’s findByContent method.
- Lay down the foundation for bootstrapping the Ember app.
- Update Web layer’s asset manager to properly publish CSS/JS files.
- Console commands to run installation migrations and seeds.

Refactoring:
- New structure: move models, repositories, commands, and events into
their own namespaces, rather than grouping by entity.
- All events are classes.
- Use L5 middleware and command bus implementations.
- Clearer use of repositories and the Active Record pattern.
Repositories are used only for retrieval of ActiveRecord objects, and
then save/delete operations are called directly on those ActiveRecords.
This way, we don’t over-abstract at the cost of Eloquent magic, but
testing is still easy.
- Refactor of Web layer so that it uses the Actions routing
architecture.
- “Actor” concept instead of depending on Laravel’s Auth.
- General cleanup!
