Cast the revisionable ID to a string to overcome issues with Uuids

[alexhouse]

We're currently using Revisionable in a project that has Uuids for primary keys. Without this change, the IDs keep getting cast to integers, which don't work

It seems the primary key goes into the revisionable_id column in the revisions table - and this is hard coded to be an integer(11).

I'm not sure the best way to handle primary keys that don't happen to be automatically generated integers or whatever type that is assumed; some concerns including:

• Downgrading UUIDs to a string and then saving as an integer isn't likely to work properly (imho);
• The things I'm working with are all unique, primary and they're not convertible to an integer without hashing.

I guess it might be possible to have a somewhat large column (a text/a blob) to store the original primary key {stringified or otherwise encoded] and then hash the that to make the primary key (but this presumes a world where secure hashes don't have collisions).

Hi all, I'm going to be maintaining a fork that has complete UUID support at https://github.com/joshbrw/revisionable-uuid.
