.SYNOPSIS
    Update all automatic packages
 
.DESCRIPTION
    Function Update-AUPackages will iterate over update.ps1 scripts and execute each. If it detects
    that package is updated it will push it to Chocolatey repository. The function will look for AU
    packages in the current directory or in the directory pointed to by the global variable au_root.
 
    For the push to work, specify your API key in the file 'api_key' in the script's directory or use
    cached nuget API key or set environment variable '$Env:api_key'
 
.EXAMPLE
    Update-AUPackages p* @{ Threads = 5; Timeout = 10 }
 
    Update all automatic packages in the current directory that start with letter 'p' using 5 threads
    and web timeout of 10 seconds.
 
.EXAMPLE
    $au_root = 'c:\chocolatey'; updateall @{ Force = $true }
 
    Force update of all automatic ackages in the given directory.
 
.LINK
    Update-Package
 
.OUTPUT
    AUPackage[]

          Force - Force package update even if no new version is found;
          Push - Set to true to push updated packages to chocolatey repository;
          Mail - Hashtable with mail notification options: To, Server, UserName, Password, Port, EnableSsl;
          PluginPath - Additional path to look for user plugins. If not set only module integrated plugins will work;
          Plugin - Any HashTable key will be treated as plugin with the same name as the option name.
                        Script with that name will be looked into AU module path and user specified path and if
                        found, it will be called with splatted HashTable passed as parameters.
