Fixed CRM-20330: composite primary keys

[jaapjansma]

Provided a way to generate a table with a composite primary key. Because the generation of dao functionality is changed all the DAO's had to be regenerated.

This is need for the proposed solution for CRM-19934 (performance improvements around acl_contact_cache.

I took a look at this & am going for a quick merge on it for the following reasons

1. we just cut the rc so it's a good time to merge
2. there are no material file changes - it's just DAO checksums & gencode
3. I feel like this code has really good test coverage (the DAOS) and I don't anticipate any issues outside the test.

I didn't actually review the DAO generation changes in fine detail, due to the fact they aren't actually being called upon here & the 'works when a composite key is added to the xml' is a pretty good test at that point
