scdbg IDA integration

Couple new features added to scdbg this weekend.

First, I added basic IDA integration using my IDASrvr plugin. It can now sync the IDA display on break point and single step events. You can also easily add comments to the IDA database at the current address just by hitting ; from within the debug shell.

You can enable it on startup with -idasync or from debug shell with the .idasync command.

Scdbg now also supports up to 10 breakpoints. -bp can accept file offsets in addition to virtual addresses and api names.

I also added a routine to display JUMP TAKEN / JUMP NOT TAKEN when the flags register is being shown. Jump instructions now display up or down arrows to indicate the direction at a glance (^^ or vv)

gui_launcher also received a minor feature where it will save the last 50 manual arguments you used.

Also does anyone know how to select the active line of disassembly in IDA? Older versions used to highlight the selected offset when jumpto was called from a plugin. New one doesnt seem to.

Currently I am doing the following to select the current line:

jumpto(addr);
HWND ida = (HWND)callui(ui_get_hwnd).vptr;          
SetForegroundWindow(ida);//send HOME,SHIFT+END keys to sel the curline
keybd_event(VK_HOME,0x4F,KEYEVENTF_EXTENDEDKEY | 0,0);
keybd_event(VK_HOME,0x4F,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
keybd_event(VK_SHIFT,0x2A,0,0);
keybd_event(VK_END,0x4F,KEYEVENTF_EXTENDEDKEY | 0,0);
keybd_event(VK_END,0x4F,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
keybd_event(VK_SHIFT,0x2A,KEYEVENTF_KEYUP,0);
