Description:
------------
Calling Bitset::set(0) sets all bits in the bitset. This occurs even when calling Bitset::set(0,0).

Test script:
---------------
<?php
$bitset = new Bitset(8);
$bitset2 = new Bitset(8);
$bitset->set(0);
$bitset2->set(0,0);
echo $bitset->get(1) ? "bug\n" : "correct\n";
echo $bitset2->get(1) ? "bug\n" : "correct\n";


Expected result:
----------------
correct
correct

Actual result:
--------------
bug
bug

In my opinion the behaviour of BitSet::set(0) is currently just wrong. BitSet::set(0) should set the first bit only to be consistent with other calls like BitSet::set(2) which sets the third bit only. It does imo not make any sense that i have to specify the second argument just for setting the first bit only.

Sorry, i pressed "submit" to early. I've added an other pull-request (pecl-numbers-bitset/7) which fixes this behaviour.
