master now has become 2.0, there won't be another 1.6 anymore,
since the focus of the team is on the next big release now.
Minor bug fixes will be implemented though in 1.5.X.
Some reporters are aggregating the messages instead of displaying
them when they are available. The actual displaying was conflatted
in the generate_reports. Unfortunately this behaviour was flaky
and in the case of the JSON reporter, the messages weren't shown
at all if a file had syntax errors or if it was missing.
In order to fix this, the aggregated messages can now be
displayed with Reporter.display_message, while the reports are
displayed with display_reports.
Close#766 and #765
With this change, we moved away from depending on logilab-common,
having in Pylint all the components that were used from logilab-common.
The API should be considered an implementation detail and can change at
some point in the future.
Closes issue #621.
