Add uuid support

[spelletier]

Add support for auto generated UUID type 4 (random) as primary key.
Add a uuid prototype for FrontBase, MySQL and PostgreSQL. I do not have instance of other type of database to test them.
Add support for UUID primary key in ERRest.

Hi Samuel,

Would it be possible to use PostgreSQL's uuid as the external type here? Or does it create problems elsewhere?

Paul,

PG UUID seems to map to Java UUID and is a very PG specific. I do not remember having tried to map a UUID column to an NSData with EOF.

Keep in mind that EOF only supports Integer, Long, String, Date and NSData as primary key type.

  Hi Samuel,

Would it be possible to use PostgreSQL's uuid https://www.postgresql.org/docs/current/static/datatype-uuid.html as the external type here? Or does it create problems elsewhere?

Ah, thanks Samuel—it was lost on me that your overall aim was primary key support.
