Avoid forcibly loading modules

1. Any modules failing to load triggers dzil dying with "Have you
installed `@Author::JQUELIN`"

2. Forcibly loading all modules means modules that are broken block
`@Author::JQUELIN` being usable _and_ block the use of `@Filter` to avoid
this issue.

3. Forcibly loading all modules at the bundle stage makes using
`[Bootstrap::lib]` on any `@Author::JQUELIN`  distribution slightly
more problematic from time to time:
```ini
  [@Filter ...]
  [Bootstrap::lib]
  [THISPLUGIN]
```
Will of course fail here because `@Filter`s ability to avoid loading the
module is nullified.

4. `Class::MOP::load_class` is going away

5. ... and dzil will in fact load all your modules for you anyway =)
