parser: fix #59, fix 60

Fix sample.lua iteration

sample.lua did not iterate over the output of :select() correctly. It had been written assuming the keys were attributes, when in fact the keys are numbers, and the values are attributes. This caused an error when running the sample script.

Fixed #55

improved tpl-resisting and testing

Rework a bit:

 - Config API
 - Debugging
 - Fixes #50, #42 and similar
 - Reformatting
