Correspondence Pattern Annotation

[LinguList]

There are several problems resulting from the current code, mainly, because the way that everything is refreshed is not clear.

We must:

• store the selection at a given stage (which patterns by number)
• make sure that the refreshing operation works seemlessly
• use get_patterns at almost all stages

Another problem is the function that initially retrieves patterns. It is apparently not working well (giving duplicate pattern id to different patterns).
