This setting doesn't work on most platforms
including some notification daemons on linux.
Where it does work I think it is bad behavior
to default overriding their defaults anyway.
It's most valuable use was likely win32
tray balloons which no longer exist.
- Output directly to rel\ instead of to bin\ and then copying files over.
- Deduped Win32 vs x64 configs
- Moved some common properties to hexchat.props
- All build intermediates (except htm's intermediates) are no longer emitted in the source directory
