Add glColor4f(v) to Squirrel API
Fix a bug in WarpCommand constructor for destination position

The constructor has been assuming that Vec3d in Squirrel VM to be using
old internal format, although we had changed it to more efficient one.
We should have revised this issue when we changed Vec3d internal format.
glwindow: Pass GLwindowState variables to onDraw handler in Squirrel
glwindow: Add GLwindowSizeable's constructor for Squirrel

Also fixed Squirrel API documentation in initClient.nut.
glwindow: Made GLWrect's width and height properties accessible from Squirrel
glwindow: Add GLWrect's move() and moved() methods for Squirrel
Add glScissor support for Squirrel scripts

This functionality also comes with glEnable/Disable, gl{Push|Pop}Attrib
support.  Relevant macro constants are made available to Squirrel
scripts, too.
glwindow: Made scroll bars available to Squirrel scripts

We could implement them in pure Squirrel scripts, but we've already
got them in native codes.
names: Make StarEnum accessible from Squirrel scripts
names: Move warp destination window definition to initClient.nut

The scripted version can do everything the hard-coded version could,
so why we would stick to the latter?

Probably execution speed is slightly better when we use the hard-coded
version, but the most time-consuming part is the graphics rendering.
After all, choosing scripted or hard-coded here does not impact the
performance much.
names: Add ability to track and wheel move scroll bar in warp window
Make CoordSys::findcs() accessible from Squirrel scripts
names: Make warp window lists also bookmarks

The bookmarks are preset landmarks on aribitrary point in the universe.
Previously, teleport points and warp points take the role of bookmarks,
but they are hard-coded and rather inflexible.  Bookmarks are defined
in Squirrel, so you could modify almost everything about it without
recompiling.
names: Delete definition of obsolete GLWwarp

Now that Squirrel version of the window has the same functionality and
more features, we have no reason to let the class survive.
Add warpable flag to bookmarks

We want to migrate teleport points to bookmarks, but we do not want
all teleport points to be warpable.  For example, space ships should
not warp to Earth surface bookmark.
Add teleportmenu console command to show teleport points in GUI

We can reuse the window definition for warp destination window.
It's worth noting that we gained great reusability and productivity
by making it scripted.
Get rid of warp and replace teleport with bookmark in SSDs

The SSD (Stellar Structure Definition) files had been using obsolete
teleport and warp keywords.  Now we delete all warp keywords and
replace definition of teleport with bookmark.
Quit trying to find a teleport entry in warp command
