Make cinecam idle waypoints runtime-manageable

Browse Source 
Waypoints can be added/removed via chat
commands.  This makes it easier to adapt to
various "points of interest" that may evolve over
time with the world.

@ -4,8 +4,14 @@ This mod provides a more "cinematic" camera positioning system than
szutil_watch, providing a series of 3rd-party "chase" cams that move
via simple jumpcuts.
WARNING: this mod is heavily WIP and is missing a lot of functionality
When no players are online, the camera will switch to a mode where it
watches the "spawn" area, or rotating through a set of waypoints that
can be managed via chatcommands at runtime.
WARNING: this mod is intentionally missing a lot of functionality
that you would expect, like rendering the player invisible, preventing
the player from falling or taking damage, etc.
the player from falling or taking damage, etc. This is the
responsibility of other mods. See szutil_stealth for the invisibility
feature; the rest will be game-depenent.
