Clean loading UI usage. Add an extra logging flag.

Use the UI provided by the built client instead of creating a
new one. Add support for an extra `v` flag when enabling logging
via flag. An exclude function is added to the logger to prevent
outputting log lines where the content is extremely long for trace
messages. Adding the extra `v` will prevent the suppression and
all log output will be displayed.
