This commit standardizes the various todos around the code a bit in a manner recognized by LDoc. Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line: ```sh ldoc --tags todo,fixme *.lua ``` However, whether that particular usage offers any advantage over other search tools is questionable at best. * and some random beautification
