e107 corrupts form-submitted array values when GET method is used.

[CaMer0n]

Bug Description

Using GET instead of POST to submit a form with a field that contains array values, returns values in the query using the characters [ and ] . e107 incorrectly interprets this data to be an "e_MENU" debug command and corrupts the value of $_GET.

How to Reproduce

Steps to reproduce the behavior:

1. Add this query to an e107 URL: mode=main&action=custom&other[key]=1
2. Add var_dump($_GET); after class2.php

Result

$_GET has a value of =1

Expected Behavior

$_GET value should contain all the query values for mode, action and other.
