Fixes for Twitter bridge breakage on 32-bit servers. New "Snowflake" 64-bit IDs have become too big to fit in the integer portion of double-precision floats, so to reliably use these IDs we need to pull the new string form now.

Machines with 64-bit PHP installation should have had no problems (except on Windows, where integers are still 32 bits)
