Codex: CSM Profile restructuring

Version 107: Realigned profiles to fix and close bugs.

Altered Khorne Bezerkers to accomodate for issue #603. Entry updated but
profile needs tweaking to resolve the final issue.

Fixed up Plague Champion options in relation to #581. Core issue has now
been fully resolved, however work on the entry links needs retidying.

Rebuilt the Chaos Space Marine Entry to facilitate the Boltgun/CCW
options. Closes #614
