Attempts to improve forcing synergy window to foreground. These 

changes don't seem to improve the situation but don't seem to
hurt either.

// force our window to the foreground. this is necessary to
// capture input but is complicated by microsoft's misguided
// attempt to prevent applications from changing the
// foreground window. (the user should be in control of that
// under normal circumstances but there are exceptions; the
// good folks at microsoft, after abusing the previously
// available ability to switch foreground tasks in many of
// their apps, changed the behavior to prevent it. maybe
// it was easier than fixing the applications.)
//
// anyway, simply calling SetForegroundWindow() doesn't work
// unless there is no foreground window or we already are the
// foreground window. so we AttachThreadInput() to the
// foreground process then call SetForegroundWindow(); that
// makes Windows think the foreground process changed the
// foreground window which is allowed since the foreground
// is "voluntarily" yielding control. then we unattach the
// thread input and go about our business.
//
// unfortunately, this still doesn't work for console windows
// on the windows 95 family. if a console is the foreground
// app on the server when the user leaves the server screen
// then the keyboard will not be captured by synergy.
