adding urldecode_json to compliment urlencode_json and updating readme.md; slight tweak to urlencode_json from previous commit

Many deprecations since 0.8 and new commands.

This commit allows for paths with spaces to be symlinked
in Pow.

If an application is located in a folder like `/some path/to the/app`

Rendering the 'vagrant box (remove|repackage)' completion code independant of Vagrant implementation details.

Added an <esc> to the begining of everything. I ran something when I was in insert mode once and all it did was shove !args... into the buffer.  <esc> first.

Added an optional callout to the end of the interaction function. I put it in to allow me to put the window focus on MacVim / GVim depending on the different OS I happen to be on

Fixed: If you callvim on a non-existant file with a relative path, the CWD of the running gvim process is used, and that's not right.  We use the PWD explicitly instead, in this case

Emacs returns either a sequence of availbale displays or nil. Checking
nil fixes this script to work as expected.
