truncate redbox error

Browse Source 
Summary: If a redbox error is too long it's not shown at all:
{F24443416}
This diff truncates it to its first 10000 chars, which should be good enough:
{F24443417}

The reason is a limitation of UILabel which backs text property on the used UITableViewCell.
Ideally we would use a custom cell with UITextView, but I don't feel there is any value in displaying super long error messages in a redbox.
