Added a ShowMessageProcessor and a ShowMessageMessager classes to process
incoming `window/showMessage` notification and display a notification
in `float` mode in the UI if the message type is `error` or `warning`, in
the events panel otherwise. Note that the notification type for `error`
messages is incorrectly set to `Log` because of a bug in the typefox
dependency: `io.typefox.lsapi.MessageType#Log` has the value `1` instead of
`4`.
This issue depends on https://github.com/eclipse/che/pull/3113
(Add a 'warning' state for the notifications)
To test the pull request, please follow the instructions on
https://github.com/eclipse/che/pull/3123 to run the 'test-lang' server.
Once in the workspace, create a project, add a `foo.test` file (the
Language Server support for the 'test-lang' will be activated), then
type the following line
> window/showMessage:error: a message
and wait for the editor to save the changes. This will trigger a
`window/showMessage` notification from the 'test-lang' server in the Che UI.
