[Savane-dev] Removing some code from index.php

[Michael McTails]

There seems to be a bunch of code in index.php that should be considered from removal. It is used to check to make sure that the critical variables in the configuration file is set but since we are currently using Perl scripts to automatically generate a new file, they seem kinda useless. The code starts around line 30. Also, on the matters of $_REQUEST, we can solve the variables_order problem by simply adding one line of code, so we can remove the worry that the user is going to have a improperly set variables_order option. 

ini_set(variables_order,"EGPCS");
