Additional OData query options support

[stanislav-kozyrev]

By looking at ODataExpression.cs one can notice that only 4 (out of 8) OData query options are supported currently:

                case "$filter": ProcessFilter(value); break;
                case "$orderby": ProcessOrderBy(value); break;
                case "$top": ProcessTop(value); break;
                case "$skip": ProcessSkip(value); break;

It would be nice to have support for $select, $expand, $inlinecount and $skiptoken.

Because of limited time I can spend on this project I will not pick this up in the foreseeable future. However this is an interesting issue so I'll leave it open and maybe pick it up when I have more time available.
