The intention of the redirection to /dev/null is to hide the output
'hash: no such command: git' since we rely on the exit status.

However, the output goes to stderr, so it's stderr that needs to be
redirected. For completeness, we redirect both stderr and stdout using
'2>&1'.

Example:

  [~]$ hash git > /dev/null
  [~]$ PATH=''
  [~]$ hash git > /dev/null
  hash: no such command: git
  [~]$ hash git > /dev/null 2>&1
  [~]$

Fix broken reverse-menu-complete keybinding.

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.

Since e537ee9d, the reverse-menu-complete keybinding has no longer been
properly bound (it was accidentally bound to the delete key).

This commit again binds it to shift-tab.

Fixes formatting on some rare cases when a percent ends up
in the $CMD variable, like these below:

- When assigning a variable, $CMD ends up with the second parameter;
in this case, $CMD will contain '+%s%N', messing with the syntax:

 $ a=`date +%s%N`

- A function (or command in general) that contains a percent symbol:

 $ to\%() { echo $(( $1 * 100 / $3))\% } # $CMD=to%()
 $ to% 2 of 10 # $CMD=to%

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`
the powit command would fail when it shouldn't. It's not the case
anymore.

Fixes #2641, #2642
