Subject: Show current_user as the preferred schema accessor
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=refs%2Fheads%2Fmaster;p=dbsrgits%2FDBIx-Class-UserStamp.git

Show current_user as the preferred schema accessor

Fits in Better with Catalyst-TraitFor-Model-DBIC-Schema-WithCurrentUser, which
takes less code / config to get working.

However we still support ->current_user_id being called, if present, although
->current_user will be used in preference
