[FEATURE] Add "real" traceback

[ElBe-Plaq]

Is your feature request related to a problem? Please describe. When an error occurs, you don't have a great way to find, which part of the code produced it.

Describe the solution you'd like Good looking, maybe even colored Traceback, like in python or C.

Describe alternatives you've considered Keep it as it is and look up the code for yourself. (Line number and column get printed as usual)

What about something like this:

Error: Division by zero, in line 0, column 0.
Division by zero is not allowed.

1 / 0.00000
     ^~~~~

Or more like the python style:

Traceback (most recent call last):
  File "example.ilang", in line 2, column 4
     1 / this_is_zero
          ^^^^^^^
  File "example.ilang", in line 1, column 20
    var this_is_zero = 0
Division by zero: Dividing by zero is not allowed.

The arrows are not formatted properly, because of my browsers font.
