Expand on tag filters

[abrenoch]

I noticed the tags filter was a bit rigid so I have some proposed changes:

• Adds useTagIdPath as a query variable. This will allow searching for tags by their nested location (such as /7/11/15/) rather than just the name. If 2 tags with the same name existed within 2 different parents, there was no way to differentiate which one was returned. This will allow targeting specific tags within the scope of the parents.
• Adds hasAllTags as a query variable. Currently the tag filter matches any of the tags provided in the query, setting this variable to true will require results match all the tags provided.
