Gorm: Support bulk inserts of a slice of objects

[colegleason]

I'm using gorm to populate my DB with a bunch of info from a file. It would be awesome, for performance reasons, if I could insert a whole slice with one INSERT SQL statement.

+1 I am doing something similar by parsing a CSV of records.

I don't like this idea because it won't run callbacks, and save associations...

I can imagine many people will misuse this feature when have it. So maybe better write your own sql to do this job?

@jinzhu for Postgres, which uses positional arguments rather than ? for inserts, how do you recommend we build the bulk insert statement?

@calebthompson have a look at python/django orm, they already have this feature
