[Firebird-net-provider] Intellisense support

[Pierre A. <pie...@op...>]

With the 1.7 version of FirebirdSql.Data.Firebird.dll, I could generate
a FirebirdSql.Data.Firebird.xml file which helped Visual Studio in pro-
viding better Intellisense support.

I have not been able to generate the XML file for the 2.0 provider. Has
anybody some hints as to how I should proceed?
