Source code for galaxy.model.migrate.versions.0011_v0010_mysql_index_fix

This script fixes a problem introduced in the previous migration script
0010_hda_display_at_authz_table.py .  MySQL has a name length limit and
thus the index "ix_hdadaa_history_dataset_association_id" has to be
manually created.
