throw error via rocker template

[sudohalt]

There should be a template function that exits and throws an error. For example:

{{ if eq .id "a" }}
"config.file=a.xml"
{{ else if eq .id "b" }} 
"config.file=b.xml"
{{ else }}
  {{ error "invalid id" }}

@sudohalt I made PoC for your issue. If you still need it, feel free to make some tests :)
