Access pairwise alignment metadata via Multi packed file

[twalsh-ebi]

Requirements

• Filling out the template is required. Any pull request that does not include enough information to be efficiently reviewed may be rejected.
• Please consider which branch this is to be submitted against. This is usually obvious, however if it is to be applied to both a release branch nn and master then please submit it against postreleasefix/nn and let us merge it into to the two branches.

Description

This PR would change ConfigPacker::_summarise_compara_db to pack SYNTENIES metadata, and would update EnsEMBL::Web::Document::HTML::Compara::pairwise_mlss_data to use packed ALIGNMENTS and SYNTENIES metadata instead of the Compara Perl API when generating the pairwise genomic alignments/syntenies list.

Views affected

This will change how alignment information is fetched for the Vertebrates pairwise genomic alignments page.

It is not expected to change what alignments are presented, though it may change the order in which they are presented.

Example: sandbox vs live site

Possible complications

This change would require repacking of all MULTI.db.packed files.
