Also finally did some major reworking on the error dialog. Now it doesn't spawn a new wxApp and wxFrame for each and every error - attaches to MainFrame and sticks around, having exceptions append to it rather than spawn a new one. In the case that an error happens before MainFrame is available, it spins up a new wxApp. Yay cleanup!
