fuel_set_var issue when value isn't a string
I have tried adding a call to fuel_set_var where the value is boolean and it ignores the value and just issues an empty string. I tried with integer values as well with the same result. The issue seems to stem from the fuel_helper function fuel_var. My application's setting result in the marker being an empty string and the function returning the marker. I'd fix the code and do a pull request but I'm not 100% sure what the marker logic of that function is for.
