Add ConkyText

[simotek]

This is a text box that does conky variable substitution, as an easy way to get data.

By the way no need to review these in a hurry, I'm giving a talk at a conky talk at conference in Germany in a couple of weeks so i'm trying to get a bit done, i'll try and send everything in easy to review chunks although other then some sort of theme idea i'll probably slow down on submissions to you until I have the new text stuff in upstream conky

I did the rename but I didn't regenerate the docs yet because i'm guessing that will just cause mass conflicts
