Refacted ModuleInstaller.Install() to use FindInstallableFiles()

Actually, it now uses `InstallModule()`, which does the work.

Notable changes in this:

- Install() can throw exceptions again.
- We move InstallComponent() towards being deprecated
- We cry over still needing bundles.
- Closes #93

Sample output:

```
