Handle multiple filters (AND, OR) for cross filters

[metmirr]

The current implementation of cross-filtering(filtering with relations) does not support the newly introduced AND, OR feature.

I'd approach this issue by extending the core warthog toolkit by add _some, _every, _none support to warthog BaseService.buildQueryBuilder() instead of relying on the codegen. Then AND, OR support will come out almost for free.
