Fix searching for levels with name blockly

[dmcavoy]

Dan and Mike pointed out that every old style blockly level was showing with blockly as its name in the AddLevelsDialog. The name we actually want to use for these levels is in the level_num. This updates the search and levels list to take level_num into account for these levels.

this works fine for word search, but the results are pretty confusing if I am looking for a level like blockly:Artist4:3_1:

part of the problem is that the "type" of these levels is Blockly, not Artist. another part of the problem is that _ appears to be a wildcard in mysql LIKE syntax.

What I would suggest is, when the search string starts with blockly:, just look for one level where the level key exactly matches the search string, using Level.find_by_key. I can't think of a situation where a curriculum writer would want to add one of these levels, but wouldn't already have the entire level key available.

@davidsbailey Thanks for the feedback. That all makes sense and I can definitely update. Do you mind if I get this change in since curriculum needed this fixed asap and then I can update it to account for your feedback?

@dmcavoy yep, I think that makes sense given the situation.
