Changeset [1d4c0b2e5fb689b9f32098692e31a31dbf3769ab] by gregg

Filtering out splice site features when creating an Apollo JSON feature to send to server. This fixes problem when trying to create duplicate of feature with non-canonical splice site, get extra splice site feature and extra zero-length exon. Ed is implementing more robust solution on the server.
