Access keys as additional security

If 'USE_ACCESS_KEYS' are set to true only those will access RF whose url
contains the access key (akey) like:
<input type="button" href="../filemanager/dialog.php?akey=myPrivateKey">

Allowed access keys are defined in the config as well.
$access_keys must be an array so you can add multiple.
Your access key should NEVER be 'key' and keep in mind they are CASE
SENSITIVE!
For recommended key generation read the comments in the config file.

If there's no access key supplied with the url or it's not in the
$access_key array you will get 'Access Denied' and you cannot continue.

For tinymce a new variable was added: "filemanager_access_key"

Tinymce config example:

tinyinit
...
external_filemanager_path:"../filemanager",
filemanager_access_key: "myPrivateKey",
...

This is a bit of additional security so no one can access your filesystem.
