Update Devel::StackTrace from 1.34 to 2.00

Changes since 1.34:
2.00   2014-11-01
[BACKWARDS INCOMPATIBILITIES]

- The no_refs constructor parameter is now deprecated, and has been replace by
  a new unsafe_ref_capture parameter that defaults to false, meaning no
  references are captured by default. Capturing references by default caused
  too many issues that couldn't be worked around, including running DESTROY
  blocks multiple times on captured objects in the worst case.

- Removed support for the long-deprecated no_object_refs constructor parameter
  (deprecated in 2002!).
