Format on PI's and basic parser functions

PI's
So, the format tag is used to change how something is outputted. Say you want the "Years active" tab to change the output.

With normal fields, the input is the exact same as the output. Put `Katy Perry` in, get `Katty Perry` out in the infobox. ` ` just changes up the output. Put `Katry Perry` in, get `Katy Perry is awesome` out in the infobox.
