When downloading files from Koji to make a local repository, display
a temporary status of which files are being displayed to the console
appended after any log messages. Updates are done by erasing the status
that was written, adding a log message, then writing the status again.
When running in local mode, add a special handler that filters log
messages to the console to produce attractive output. Implemented
behaviors include:
- INFO level messages are only displayed if done through
MBSLogger.console() rather than MBSLogger.info().
- Timestamps and thread names are omitted unless the local build
is started with the -d option
- Warning/error messages have the level highlighted in red
- Special handling can be added to log messages, initially:
- Long running operations can be displayed to the console as
"Doing foo ... <pause>done"
This also includes `from __future__ import absolute_import`
in every file so that the imports are consistent in Python 2 and 3.
The Python 2 tests fail without this.
