2.5: Error reporting

* Added a report list to operator, to which they can report errors and
  warnings. When the operator ends, it will display them with a popup. For
  python these should become exceptions when calling operators.
* Added a function to make a popup menu from a report list.
* Also added a utility function to prepend a string before the reports to
  indicate what they relates to. Also made the report functions used
  BLI_dynstr to simplify the code.
* Made file reading and writing report errors to the user again using this
  system, also replacing the left over uncommented bad level error() calls.
