Feature: Add compile error messages as marks within in the editor

[MarkOates]

This would likely be broken down into adding error messages during different stages of build.

• Test failures as marks in the editor
• Quintessence error messages as marks
• C++ compile error messages (source/header line numbers would need to be offset into quintessence line numbers)
• Differentiate the errors and the warnings

Quintessence build error messages would need some new error data:

• Add filename to the "undefined symbols for datatype"
