Request for comm(en|i)ts: Decoupling daemon from unvanquished

[TimePath]

Summary: CMakeLists changes to reduce coupling between daemon and unvanquished.

• Symlinks have been used to test the tree structure and avoid moving and copying the rest of the repo.
  • To merge, replace with the file they point to, and make '/unvanquished' the root.
• Daemon no longer contains unvanquished assets and can be packaged separately.
  • FIXME: Linux packaging scripts are currently duplicated, probably remove the ones in daemon.
  • FIXME: So are the travis-ci scripts
• Mods can target daemon in a few lines (with the prerequisite variables set):

    ...
    add_subdirectory( daemon daemon_build )
    ...
    include( DaemonGame )
    GAMEMODULE( NAME sgame
      COMPILE_DEF BUILD_VM BUILD_SGAME
      FILES ${SGAMELIST}
    )

• Testing/compiling unvanquished remains unchanged.
  • Though in this preview, you will have to cd unvanquished first.
• Daemon can easily be used as a git submodule.
  • Recommend splitting into its own repository at some point; duplicate it and remove daemon from one and unvanquished from the other.

Future improvements:

• A CMake defined branding instead of hardcoding "unvanquished" in the engine; DAEMON_BRANDING or similar.
• Stop depending on the dependency bootstrap provided by dl.unvanquished.net.
• Build daemon dependencies individually from individual repositories.
• Expose common engine/game code as a library?

Gamelogic as the submodule: With gamelogic as the submodule, it would have to be updated every time it changed. With daemon as the submodule, this is also true, but far less frequent.
