Show actual datatype and parameters in instance descriptions

[pgunn]

When you visit a repo and see the instance list, for some types it shows their actual name (like imagetile). For others it breaks that apart into logical components (like "array" "8bit"). For none of them does it make it apparent what the parameters used to create that instance were, making it hard to look at one as a guide for how to make others. It'd be great for the WebUI to show this again (even if all it does is provide a handy link to the APIcall to get the JSON description)
