Enable use of {@pod.*} in pick where options

[pcfreak30]

This is adding 1 line of code to pick.php around line 2043 if ( ! empty( $params['where'] ) && (array) $options['table_info']['where_default'] !== $params['where'] ) {

since the @pods magic tag assumes a global, setting $GLOBALS['pods'] = $pod; allows this to work.

However since im not a fan of blindly trampling over global variables I think pods_v should check for another source for the pods object.

My use case has been exchange.ID is null or exchange.ID = {@pods.ID} to only allow a related item in a relationship to show that matches the current pod item or is not linked to one to prevent "in use" items from showing up in a list. Overall this is highly useful for dynamic where queries with "introspection" without the use of php filters or tag filters.

why not create an PR for it ;) sounds reasonable - but maybe @sc0ttkclark has objections ^^

i solved a issue like that with a custom where relationship_field.ID IN( "{@get.post}", "" ) so not sure if this is needed ;) Thoughts?
