EWeb 0.51

Pages with large pictures no longer hang the Falcon (yaary.music): a picture set to a width of 100% in a grid or flex column no longer makes its column as wide as the picture's file, and pictures from the Pi are never asked for wider than the window. Quitting is quick again: the cache's index, the cookies and the history are written over in place, each in two files (EWEB.ID2, COOKIES.TX2 and HISTORY.TX2 beside the old ones), instead of as new files at every quit, which took 33 s on a real disk after Wikipedia; the first quit after updating still makes those files once. One click on a window's scroll bar moves it one step on TOS 4.04 (it moved two). The ST edition draws text, fills and the screen faster: a news-size page draws in 3.7 s instead of 6.1 on an 8 MHz ST.
