Fix some issues with hooking into dependencies

- Directly use list of dependencies from Dependency enum instead of the one defined in plugin.yml to be able to hook into plugins not depended on
- Add ability to check for correct version of a plugin via the author name as some people "steal" plugin names...
- Fixed that a plugin's "provides" declaration was only taken into account for plugins already loaded on startup, not when they enabled later
- Made the message when a dependency was hooked into less confusing
