Subject: [PATCH 1/2] Fix missing sliced_for_model migration (Issue #211)

The sliced_for_model column was added to the PrintArchive model for
model-based queue assignment but the database migration was missing.

This caused upgrades from 0.1.6b11 to 0.1.6 to fail with:
"no such column: print_archives.sliced_for_model"

Users' data was not deleted - just inaccessible due to query failures.

Subject: [PATCH 2/2] Fix missing sliced_for_model migration - for real this
 time (Issue #211)

PR #215 claimed to fix this but the actual ALTER TABLE migration was
not included. Users upgrading from 0.1.6b11 to 0.1.6 still see:
"no such column: print_archives.sliced_for_model"

This commit adds the actual migration that was missing.

Closes #211
