Merge branch 'develop'

* develop:
  Update changelog
  Issue #12: Fix incorrect quoting of column wildcard. Thanks pewterfish.
  Add MySQL-specific connection example in README
  Fix out-of-date comment and typo in README
Add support for raw `ORDER BY` clauses.

This is useful when you need to order results by something other than a
column name, like the output of an SQL function.
Allow raw queries without parameters

This is useful for e.g. MySQL `LOCK TABLE` or SQLite `VACUUM` commands
which usually do not require parameters.
Update multiple properties at once

This change alters the `set` method so you can update multiple
properties at once, by passing an associative array top `set`.
Rename order_raw to order_by_expr
configure() function can now accept an array of settings (also updated README to reflect this)
