Is lineno within the template?

Jinja has decent exceptions, I feel like we should just show the actual erroring bit of the template

--- nvm tested the wrong thing :p kept getting caught in the python template wrapper :p

New tests
correctly identifies the line within the gcode: section

works with whitespace (unlike the python wrapper)

I can confirm that this also works on my machine

though, i do think that it would be better to have the line of the whole file. which in that way it would be faster to find the error because now you'd have to find the macro first. So line 375 in this example

unfortunately it is not possible at the moment due to includes and ordering of it happening..

thanks all for the test
