gitk: New way of constructing menus that allows for Alt+letter accelerators
This is inspired by patches from Robin Rosenberg but takes a different approach. This adds a "makemenu" procedure for constructing menus that allows the menu layout to be specified in a clear fashion, and provides one place where the alt+letter accelerators can be detected and handled. The alt+letter accelerator is specified by putting an ampersand (&) before the letter for the accelerator in the menu item name. (Two ampersands in succession produce one ampersand in the menu item as it appears on screen.) This is handled in makemenu. We also add an mca procedure which is like mc but also does the ampersand translation, for use when we want to refer to a menu item by name. The mca name and the locations where we use it were shamelessly stolen from Robin Rosenberg's patch. This doesn't actually add any alt+letter accelerators yet.
