app-map runtime tags

[Isaak-Malers]

Add functionality for "tagging" A node on the app-map with information about its past run-time.

this will look something like:

meta:{
  "runtimeTags": {
     "lastUsed": "date",
     "lastError": "error string",
     "lastErrorDate": "date",
     "useCount": "an incremented value"
  }
}

This will allow the "search" function in the UI to do some fancy stuff such as, automatically showing errors, and automatically showing "depricated" nodes, which maybe haven't been used in quite a while.
