Clean up the Utils namespace in 2013 because most everything was re-distributed into other namespaces during 2010 refactor

[taoneill]

Make sure no 2013-specifc changes get manually merge into their new-namespace'd counterparts (e.g. if anything changed in Utils/FieldHelper since October 2013, it need st obe incorporated maybe into the new Definitions/FieldHelper)

Check out the 2013 history of these in particular:

    <Compile Include="Utils\FieldHelper.cs" />
    <Compile Include="Utils\FieldInfo.cs" />
    <Compile Include="Utils\IResourceLocator.cs" />
    <Compile Include="Utils\ListHelper.cs" />
    <Compile Include="Utils\ListSecurityHelper.cs" />
    <Compile Include="Utils\MasterPageHelper.cs" />
    <Compile Include="Utils\MuiHelper.cs" />
    <Compile Include="Utils\NavigationHelper.cs" />
    <Compile Include="Utils\RegionalSettingsHelper.cs" />
    <Compile Include="Utils\ResourceLocator.cs" />
    <Compile Include="Utils\SearchHelper.cs" />
    <Compile Include="Utils\SecurityHelper.cs" />
    <Compile Include="Utils\Unsafe.cs" />
    <Compile Include="Utils\VariationsHelper.cs" />
    <Compile Include="Utils\WebConfigModificationHelper.cs" />
    <Compile Include="Utils\WebPartHelper.cs" />

Going through each one, looks like the merge worked properly and that nothing was lost.
