Maze - Should be more consistent

[litemerafrukt]

If you try to enter the maze before you selected a map you get an answer with: text: "Map not selected" and response code 500. Would be more consistent with other errors if changed from "text" to "error".

Na, its more like "error" is the "index" that should be changed instead, regards to consistency. Its only used two times throughout the hole program: https://github.com/mosbth/linux/blob/master/example/nodejs/maze/maze.js#L269-L280

Ok :smile:

But we can change the "error" to "text" instead.

For consistency change response type to 'plain' on: https://github.com/mosbth/linux/blob/master/example/nodejs/maze/maze.js#L225

I'll fix that.
