Master

* EGPairAligner_conf.pm - already done by Stephen - disregard that

* EGProteinTrees_conf.pm - some more specific resource classes for Plants hom compara

* table.sql - adding homoeologues support to the schema
* populate_member_production_counts_table.sql - count homoeologues

The two latter should be added to ensembl-compara master branch only.
