Revert "exclude unnamed Library/Executable from ide integration"

This reverts commit 93cd7b78.

We need to generate project files for unnamed projects as they seem to

integration (which seems strange) then we need to handle these problems
in the MSVC generator and not in the parser.

It also includes:

Revert "Clean trailing whitespace"

This reverts commit 7d92b27a.
