[SQLObject] Preparing for 0.5

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

I don't think there's much left before 0.5, and there's a lot of
bugfixes that should be released in a proper version.  In Firebird and
SQLite there is the string quoting issue, which has to get fixed (along
with booleans).  Are there any other things that I'm forgetting about?

Also, someone mentioned PyGreSQL support at some point, but I lost the
details.  I tried adding it, but it acted weird, and I didn't try very
hard.  Can anyone test what's in CVS and see what needs to be done? 
Does anyone care about PoPy?

Firebird also still has the cursor issue, but I think it's otherwise in
good shape.
