Title: Set correct AppData dir for more Windows versions

Replace the hard-coded path with an environment variable supported by all versions of Windows since XP (`%APPDATA%` in Windows, `$APPDATA` to Vim).

By default, Windows XP stores Application Data in the folder:

C:\Documents and Settings\\Application Data

Windows Vista and later store AppData in:

C:\Users\\Application Data

or

C:\Users\\AppData\Roaming

You can, if you really need to, read all about the gory details of AppData here:
