Cleanup and simplify boot process messages

- Remove indentation of module loading and device node creation
- Clarify that we load kernel modules
- Clarify that we load Finit plugins
- Remove cls()
- Remove verbose condition for echo()
- Make banner a separate function with optional distribution banner
- Add a few neat ANSI escape sequences for cls(), clreol(), delline(), etc.
