Adds a new PlatformID for universal builds. This will allow single architecture
builds to be updated through the single architecture path, and universal builds
to be updated with universal builds.
Any file which includes scmrev.h must be rebuilt when scmrev.h
is regenerated. By not including scmrev.h from any file other
than Version.cpp, incremental builds become a little faster.
This function does *not* always convert from UTF-16. It converts
from UTF-16 on Windows and UTF-32 on other operating systems.
Also renaming UTF8ToUTF16 for consistency, even though it
technically doesn't have the same problem since it only was
implemented on Windows.
The AutoUpdate module is a generic update checker mechanism which can be
used by UI backends to trigger an auto-update check as well as the
actual update process.
Currently only configurable through .ini and the Qt implementation is
completely placeholder-y -- blocking the main thread on a network
request on startup, etc.
