As indicated in a code comment, destroying and rebuilding all snippet
editors when a snippet is moved is more accurate as the snippet options
may depend on the new locations in a way the 'onMove' callback cannot
handle. That operation seemed however too costly for no visual benefit
at the time. Now, not implementing it is a source of bugs and redundant
code (as with the new "number of columns" option which is not properly
updated once a column is moved in another row), so this commit
implements the feature.
This also allows for some improvement: the 'cleanForSave' part of
snippet editors is always performed when they are destroyed.
If this proves to be ok and safe, we might want to backport this in
previous versions.
