(QENG-251) Beaker should be able to run the PE installer in debug mode

- add verbose mode for linux/mac and win installs.
- add '-x' for bash frictionless installer
- fix issue with non-UTF-8 encoded characters generated in windows logs
If you want to modify the `msg` parameter it's probably best to be explicit about the `Beaker::Logger.debug` method parameters, ie:
```
def debug msg, add_newline = true
  strings = convert msg
  optionally_color WHITE, strings, add_newline
end
```
