Default focus is now on the button that also reacts to the 'Enter' key. This should avoid confusion about Enter triggering the button1 or button 0.
Also, I changed the shortcut call to the new convention which works on MSWindows. I don't have a Linux system right now for testing... .
Fixed focus issues (STR #1286, STR #1289, STR #1296)
fl_xfocus was not always updated, making widgets or even whole windows loose focus when any focus changes were not accompanied by a click into the same window. Also, Fl_Tabs would not redraw correctly if focus returned to the active tab.
