Modify to use vssettings file for loading

[zbrad]

A current limitation of the original version, is that it requires the copying of a "vsk" file, into the Visual Studio product folder, which requires running the extension installer as administrator.

To solve this, my next check-in will instead make use of the Visual Studio import/export bindings (vssettings), stored per user, with a specified set of Emacs key bindings, that can then be edited locally according to taste.

@zbrad will this version work with Community 2013?

I'm not sure if community allows extensions, but if it does, it should work fine.

This is a good idea.
