Support object related magic tags in field WHERE clause

[JoryHogeveen]

Issue Overview

Currently object related magic tags only work in templates (eg: {@post_parent}.
It will require some refactoring but it would be awesome to support these type of tags within the WHERE clause for relationship fields.
For example: t.post_parent = (@post_parent}.
For new posts this should return the default value for that object. (in case of post_parent it would be 0).

Current Behavior

These tags return nothing and result in a query error. ( t.post_parent = ). If it's empty I guess the it should be ( t.post_parent = '' ) or ( t.post_parent = 0 )

Possible Solution

Before doing pods_evaluate_tags check if the tag is related to the current object, if so, pass the object so pods_v can find the value.
