De-sluggify Function

[rfox90]

"Though what I'd really like to have is a field where I can specify the name of the function which should be run with title as an argument. This way the user would be able to grab the actual title from the database. It makes a difference when the title has non-standard letters like "Żółta żaba żarła żur", while the slug looks like "zolta-zaba-zarla-zur". Or when the title we grab from route is just _id." @brajt

Sounds good.
