Remove limit on Taxon tree relationships by rank

[grantfitzsimmons]

Currently in Specify 7 and 6 you are restricted to only seeing the taxon full name and author for each rank. This restriction causes issues when it comes to running a query from the collection object or creating reports and labels where you want to reference a specific field for a specific rank.

In this case, I am reworking the University of Washington's labels to reference the family number, stored in a text field at the family level.

There is no way to reference this number without using relationships through the "Parent Taxon" several times and hoping that the parent is the family. For their database, all specimen records are determined to species at the moment, but this is going to change in the future and the flexibility is necessary. I have to stack parent relationships to ensure that it will not be missed.

From what I remember Ben told me, this restriction was put in place artificially just to match the limitations of specify 6 (yeah, this is from the dark dark days where sp7 was limited just to not outcompete specify 6)

Here is the code for that:

specify7/specifyweb/stored_queries/queryfieldspec.py

Lines 27 to 30 in f4cd803

	TAXON_FIELD_RE = re.compile(r'(.*) ((Author)|(GroupNumber))$')
	# Look to see if we are dealing with a tree node ID.
	TREE_ID_FIELD_RE = re.compile(r'(.*) (ID)$')

(it currently allows only Author, ID and Group Number fields - and full name implicitly if field name was not provided). Modifying that code and lifting the restriction on the front-end should fix this

Let's remove that code...
