Speed up - too much (unnecessary) includes

## Bug Report

**Current Behavior**
Currently flarum is loading over 450 files per page (with standard extensions enabled).
That is a bit too much and costs much unnecessary time.

Example: swiftmailer are never need on the frontend, its only to send mails in cronjobs, after sending a post etc., no need to load these 17 files on every page.

**Expected Behavior**
Make sure that only files are loading that used on the requested page.

**Environment**
- Flarum version: 0.1.0.beta.7.1

```
total: 0.218 sec (fast but it could faster)

Start by profiling the request from index.php through vendor/autoload.php and the Flarum server entry points listed in the report, including Forum/Server.php, Http/AbstractServer.php, and Foundation/AbstractServer.php. Trace why service providers and SwiftMailer files are included for a frontend request, then compare the resulting file list with the current 450-file baseline. Done means avoiding unnecessary frontend includes without breaking mail or other requested-page behavior.
