[Firebird-net-provider] Classical firebird connection string support is now in CVS

[<car...@te...>]

Hello:

I have modified GdsAttachParams.cs for bring to work the code, 
originally ported from Jaybird, for allow the use of classical
connections strings of Firebird, like:
	Database=localhost/3050:D:\TESTDB.GDB;User=SYSDBA;Password=masterkey;Dialect=3;...

or
		 
Database=//localhost:3050/D:\TESTDB.GDB;User=SYSDBA;Password=masterkey;Dialect=3;...
	
The database value will be parsed with this format when no specific 
datasource element was specified.

(If i'm not wrong the second format is Java-Like, but as the code is 
ported from Jaybird i will allow it too)
