Don't crash when the HTTP request for getting the server status message fails
This fixes the crash that keeps Windows 7 users out of the game when support.cyanworlds.com is down, reported with some regularity e.g. at http://mystonline.com/forums/viewtopic.php?f=40&t=27352 .
Apparently on Windows 7, unlike on Windows XP and contrary to its documentation, WinHttpReadData() does not zero its lpdwNumberOfBytesRead argument when called with an invalid request, so the lack of error checking here bites.
and reenable as much USE_BINK_SDK stuff as empirically needed to get the Yeesha intro movie cave to disappear on its own, as before merging Cyan's Build 918.
Not the cleanest way, but I'm trying to minimize effort spent on this until we can get the proper solution, VP9 video support, from https://github.com/H-uru/Plasma/pull/458 .
- plCCRMgr.h which is still needed by plAvatarMgr.cpp (plCCRError only - if there is more in this file at Cyan, that definition should be split out into a separate header)
- Stubs for pyCCRMgr{|Glue|Glue2}.cpp which are still part of the pfPython project as well as pfCCRConsoleCommands.cpp which is still part of the pfConsole project. This is under the assumption that these files still exist with nontrivial contents at Cyan - if not, they could just be removed from the projects. Requires adjustment by Cyan to build with PLASMA_CCR_RELEASE.
- Put more missing includes and calls under #ifdef PLASMA_CCR_RELEASE
