[SQLObject] UnicodeCol

[Ian B. <ia...@co...>]

I was going to add a FAQ entry about unicode, but then it had a bunch of 
code, and I figured I should just include the code.  Now there is a 
UnicodeCol, mostly the same as what Oleg described before.

This doesn't solve the query issue, since queries involving unicode will 
fail currently.  There's a couple ways to do that:
   * Process-global encodings, added to sqlobject.converters
   * If we move to database parameters instead of building SQL textually,
     we could do per-database default encodings.  The dbconnection
     instance would loop through the parameters and convert any unicode
     strings it found.
   * sqlbuilder.SQLObjectField could pay attention to encoding.
     Actually, I want to get rid of the .q stuff, and just make
     cls.column into a descriptor, so that when fetched from a class it's
     an object that can be used in a query.  But either way this is
     fairly doable.
