cfengine3 (#766)

* Fix CommentPreproc

Macros (i.e.) CommentPreproc need to be anchored as they are only
allowed to be put on the start of the line. This also solved the
conflict with nakedvar @(....).

* Fix NameClass

NameClass (`xxx::`) can _also_ contain variables, so add " and $ to the
allowed list in the regexp. This now also needs to be put earlier to
match before any strings.
