This captures crashes on Windows along with the stack backtrace. On Linux (fedora 21 at least), the necessary function to enable capture is not included in the system wx libs. But, a self built version works fine and capture the backtrace, so I'm assuming other distros will probably work as well. On OSX, the crashes are caught, but it does not include the backtrace. But, really, the backtraces aren't all that useful in a release build since we don't ship with debug symbols and optimization plays havoc with proper backtraces anyway. The real benefit will be for the support folks as they can now get consistent info from user by asking the to generate a report from the "Help->Generate Support Data" menu item.
