Metabot should set permanent key prefix/suffix IDs

[1ec5]

The wiki’s “Key:” pseudonamespace contains some articles about key prefixes and suffixes (aka namespaces and subkeys). Recently, these articles have been formalized by including a wildcard character in the title and introducing the {{KeyPrefixDescription}} and {{KeySuffixDescription}} templates. By request, I’ve also created permanent key prefix ID (P52) and permanent key suffix ID (P53) with the intention that prefix/suffix items should use these properties instead of permanent key ID (P16).

The metabot code needs to be updated to set the new properties:

sophox/metabot/metabot/Properties.py

Lines 197 to 200 in e77056d

	P_KEY_ID = Property('P16', 'key-id', 'string')
	P_TAG_ID = Property('P19', 'tag-id', 'string')
	P_REL_ID = Property('P41', 'rel-id', 'string')
	P_ROLE_ID = Property('P21', 'role-mem-id', 'string')
