This change will add an extension point which allows to wrap the source tree. This is required in order to use a context provider e.g. to capture a selected file. Another extension point allows to add a row between the row of a file.
In order to implement the extension points ui-extensions has now a wrapper property and passes the children of an extension point to implementing extension.
It should also be possible to create new files in empty non-initiated repositories with the help of scm-manager/scm-editor-plugin/pull/39. So that the plugin can mount itself, a new endpoint was provided hereby.
