many changes, see description [skip ci]
Note: currently only works via manual injection, Rundll32Entry has been removed - Fixed conflict with UpdatePack7R2 (and WuaCpuFix) by hooking `RegQueryValueExW` and fixing the path to `wuaueng.dll`. (fixes #100) - Eliminated lots of redundant and unnecessary code. - Other reliability improvements and bug fixes. - Removed the error message that displays in the installers when `wuaueng.dll` is below the minimum supported version, and added an internal check that will skip the patching procedure if the version of `wuaueng.dll` is too low. **This means you can now safely install wufuc prior to any updates, and it will automatically start working once it's needed, without any potential side effects.** (fixes #99) - Added `/UNATTENDED` flag to the batch installer and uninstaller. You can use this to bypass the confirmation for a fully automated installation/uninstallation. To use it, you invoke the batch script from an elevated command prompt, like so: `"wufuc_installer.bat" /UNATTENDED` - Improved logging framework to allow multiple processes to safely write to the same `.log` file.
