nit: drop the header, no need since it's included elsewhere

[Rafał Chłodnicki, 2013/09/28 10:05:47]

What do you mean that it's included elsewhere?
I thought that pretty much the only reason headers are added to the list of
files is so that IDEs (thinking of Visual Studio primarily) can recognize that
the file is used by the target.

[jam, 2013/10/01 16:13:19]

I mean content_switches.h is by definition included in target in content. So if
another module outside needs the cc file, it doesn't need to relist the .h since
the IDE will already be able to find that header.
