visual, :wsudo and :esudo can now be run with :sudow and :sudoe, fixed
a few issues where gvim settings wouldn't be enabled if gvim was started
using :gui in command mode, = now does what + does so you can use - and
+ without holding shift for the + part, the ctrl/shift
up/down/left/right + h/j/k/l stuff now works the same for both using the
behaviour I suspect most people will expect from them, a 'lot' of
behaviour that didn't work in tmux should now work provided tmux is
using xterm-keys and has its $TERM set to screen*, a bunch of new
default settings have been added to settings.vim (though they're mostly
subtle or behind the scenes tweaks) and it's commented and organized
better now too, and the gvim menubar no longer appears by default (but
you can toggle it with <Ctrl><F1>)
