Runtime errors

[sovdeeth]

Description

Creates a RuntimeErrorProvider interface that SyntaxElements can implement in order to throw runtime errors and warnings.

Currently a rough proof of concept available for feedback.

Future plans include:

• a notification for online admins with a given permission, telling them to check console.
• a try-catch-esque method of suppressing and catching runtime issues
• the ability to get the last runtime issue as a string.
