XAccc7xxx: Unhandled MSBuild Exceptions

Exceptions that have not been gracefully handled yet. Ideally these will be fixed or replaced with better errors in the future.

These take the form of XACCC7NNN, where CCC is a 3 character code denoting the MSBuild Task that is throwing the exception, and NNN is a 3 digit number indicating the type of the unhandled Exception.
