Various changes.

Serialization improvements (now deserialization works).
Chunked memory stream writer is using invariant culture, so it's not required to pass it everywhere explicitly.
Oracle reader.
LINQ improvements.
Oracle support for SQL - multiple columns instead of VALUE(X) for object type.
Basic improvements on subqueries - a lot more work required.
Postgres SQL injection fixed - pass through ConstantExpressionVisitor always, now that Npgsql is fixed.
Removal of dead code. Old Pg reader/writer should be removed completely. Few usages remaining.
Added AOP plugins and support in container.
If Revenj.AllowAspects is true intercept every service resolution and add aspects around it if registered.
Repository API fixes, use Query instead of FindAll, rename SearchAll to Search.
Added missing PdfConverter binary - release tool as open source.
Merge pull request #10 from rpetrano/master

Fixed connection closing and RestApplication.svc in Mono.
Removed Oracle dependency from Wcf project.

Dont compile Oracle for now (since it has 32/62 bit issues)
