Crash report

[birdzix]

Configure an opt-in crash-report system for Xi-CAM.

• If a crash occurs, ask the user if they would like to send a crash report to us.
• Add this configuration option to Xi-CAM's settings.
• Each run of Xi-CAM should create a new timestamped log file.
• Where does this crash report get sent to?

Potentially create a MetricsPlugin that captures this functionality, as well as providing the host OS, Xi-CAM version, report generator, etc.
