":macmenu" command, etc.

First of all: the ":macmenukey" command is now deprecated...if you use
this command make sure you update your .gvimrc files or you will get
annoying warnings when you start the new snapshot.  The replacement
command is called ":macmenu", check the help files on how to use it.

This new command has allowed me to make the menus slightly more OS X
like in that you can now set "alternate" menu items.  To see what this
means, click on the "File" menu and while it is still open press the Alt
key.  The ":macm" command also enabled me to make open and save dialogs
behave better with undo/redo/select all/paste (but cut and copy probably
still do not work, I will address that soon).  I have also changed back
"File.Close" (or <D-w>) so that it now is a "normal" menu item that
sends ":conf q".

Two issues that have caused lots of confusion in the past will probably
be resolved now.  The first is the Logitech Control Center, which should
now work with MacVim.  The second is that the default setting for the
'backspace' option now includes "indent,eol,start" (I hope this won't
offend anybody too much, if it does then ":set bs&" is your friend).

Finally, by popular (?) demand I have changed the open and save dialogs
so that they now open up on the pwd (present working directory) of the
current Vim process.  Hence, if you type ":cd ~/Documents" and then hit
<D-o>, the "open files" dialog will open up inside the "~/Documents"
folder.  The default OS X behaviour is to remember the last directory
browsed to; if you prefer this behaviour you can set the user default
"MMDialogsTrackPwd" to 0.
