Load step i18n files in the grading tool
Added annotator node grading display with enlarge view option
Added AnnotatorNode to nodes with large student work in wise.properties
Slightly changed behavior of minimum labels setting in annotator - step now allows less than minimum number of labels

- For now, simply use the minimum labels setting to check for completion
- Also, set the default minimum label value for annotator steps to 1
Set svg-edit to only check for max draw size limit for draw nodes (not annotator nodes)
