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:

  [@Filter ...]
  [Bootstrap::lib]
  [THISPLUGIN]

Will of course fail here because @Filters 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 =)
