Add tooltip support to config editor via _TIP convention

ObjectEditorPanel now looks up a static String constant named
FIELD_NAME_TIP (e.g. myField → MY_FIELD_TIP) on the ConfigObject after
calling getEditor(), and sets it as a tooltip on the editor panel.

No changes to ConfigObject's API — existing getEditor() overrides
continue to work and automatically receive tooltips.
