pass details to eval_exceptions for getting an object

Browse Source 
This adds the current file, line and column to an exception thrown during object lookup.

Tested with `chai.eval("puts(bogusvar[0])")` and `chai.eval_file(file_containing_the_same)` and it printed the line and filename/`__EVAL__`.
