Fix forgotten variable initialization.
Explicitly specify __cdecl convention in API declaration.

It's the default with all sane compilers, so this is just a convenience
for people compiling their code with __stdcall as the default for some
reason.
Update copyright years.
Add x64 build configurations.

Fixes #12.
Regenerate project files.
Don't skip versions when checking manually.

If I chose "Skip version" it should not prompt me for automatic updates,
but if I explicitly open the dialog using
win_sparkle_check_update_with_ui() it should still show that version.
This is the semantics in Sparkle for Mac.

Fixes #26.
Add instructions on how to use submodules to README.
Fix outdated build instructions in the README.

Fixes #28.
Fix syntax error in WIN_SPARKLE_CHECK_VERSION macro.

Remove superfluous '('.

Fixes #7.
VS2012: use v110_xp toolset.

This ensures that WinSparkle.dll is still usable on Windows XP, for
users of VS2012 that need to ship for XP.
Regenerate project files.
Rename 3rdparty projects to include "WinSparkle" in them.

This makes using the projects in a parent solution a bit cleaner.

Add support for HTTPS downloads.
Add win_sparkle_set_app_build_version().

This allows using internal build number for comparing versions and
another (shortVersionString) for display to the user, as on OS X.
Increase version to 0.4, update release notes.
Added callbacks for shutting down the host

You can now set up winsparkle with two callbacks:
ShutDownPollCallback and ShutDownRequestCallback.

ShutDownPollCallback asks the application if it's ready to shut down

ShutDownRequestCallback shuts down the application.

These can be set by implementing the functions and calling

win_sparkle_set_shutdown_poll_callback(&shutDownPollCallback);
win_sparkle_set_shutdown_request_callback(&shutDownRequestCallback);

If this is not set, WinSparkle will not try to shut down the host.
Added missing reminder to fix implementation
Provide UI when waiting for host app

Now we continuously poll the host if it's ready to terminate (every .5
second) in a thread while displaying an indefinite progressbar to the
user and telling him that we are waiting for the host to terminate.
