set PDO character encoding to UTF-8

[richjoslin]

In the config.ini, we need to add this line:

db.rivety.config.driver_options.1002 = "SET NAMES utf8"

Without this, even with the db, tables, and columns all set to utf8_general_ci collation, all data returned by queries using PDO are converted to ISO-whatever encoding and messing up many of the special characters.

Weeeeeeeeird. Okay, we should put that in the installer and the template config.ini.
