[nant-dev] Solution task fixes checked in

[Matthew M. <ma...@ac...>]

For those interested, some recent bugfixes checked in:

 - Generate the correct filename for .resx files without dependent files 
(ie: x\foo.resx in project "some.namespace" -> 
some.namespace.x.foo.resources)
 - Convert the requested configuration to lowercase to match the rest of 
the solution building process
