List of canned comments as a drop down list

[dbitouze]

When a moderator uses canned comments, a popup window appears containing all the comments to be chosen, separated by a blank lines. Because they may be numerous and long, that's not very handy. By contrast, e.g. for "close" and "report" actions, the moderator is asked to choose a reason in a drop down list, and that is pretty handy.

It could be nice for canned comments to have the same feature as "close" and "report" actions.
