Sod will_paginate library

The old named_scope patches for 1.2.6 had issue. Basically it would remove the scope of the proxy owner at certain time. Very odd bug but I found it while creating my GroupedScope plugin and uses WillPaginate's named_scope patches in my 1.2.6 app.

This patch updates NamedScope to the latest an has two patch files for 1.2.6 and 2.0.4. I have even updated the rake test_all to use 2.0.4 and not 2.0.2. There is an odd bug when running the tests for 1.2.6, for some reason the mocha setup from its test case was triggering the ArrayPaginationTest to start loading fixtures. Since there were no table names, it had an argument error since Fixtures were converting nil to an empty string and table_names ended up looking like this [""]. See the full error below. My solution was to add an empty setup to the ArrayPaginationTest so that mocha would hit that.

Right now all tests are passing for all rails versions.

1) Error: test_argument_error_with_params_and_another_argument(ArrayPaginationTest): ArgumentError: interning empty string
