Title: adapt for new labels.yaml file format

platform: 2.1.5, 2.0.4
backlogs: master
ruby: 1.9.3

somewhen yaml behavior changed and now new downloaded labels are stored with class information. Upon loading we do not get a hash but the !ruby/object:BacklogsPrintableCards::CardPageLayout class instances.
Existing labels.yaml, stored without class information, are still loaded as hash.

Fixes my problems with running tests, fixes using labels on my 2.1.5 on ruby 1.9.3 test instance. also most probably fixes 2.1.2 installations.
