Cook a GameData/*.dll update tool. #5

The tool should:

• Be standalone, so it will be run even if 666_ModuleManagerWatchDog.dll is absent
• Will check for the presence of 666_ModuleManagerWatchDog.dll and install it from our PluginData if absent, or will update it if older.
  • Remove the original when the job is done. Be failure resilient (it may run from a R/O filesystem or something)
• Will check for the presence of 999_Scale_Redist.dll and install it from TS' PluginData if absent, or will update it if older.
  • Remove the original when the job is done. Be failure resilient (it may run from a R/O filesystem or something)

Should do nothing if the original files does not exist (saving a bit of I/O on the process).

see the following issues for the reason:

• Extract the Sanity Checks in their own DLL. TweakScale/TweakScale#254
• Special Deployment for Curseforge due Scale_Redist TweakScale/TweakScale#255
