dvbchanneleditor is not included in backend only build

[hp-mythtv.org@…]

If I want to build a BACKEND ONLY, the linker errors with references to DVBChannelEditor. Backend and frontend combined builds work.

Linking problem with MacOS X porting compile.

(In [7216]) Fixes #290.

The "bug" was caused by [7045], which made the setup a backend option without adding the channeleditor stuff to libmythtv.pro.

This commit adds the applicable files.

I'll just point out again that the --disable-backend/--disable-frontend _advanced_ options are in place only to help porting MythTV to other platforms, especially MacOS X. They are not intended nor designed for building "lite" versions of MythTV.
