[WIP] AppVeyor updates

[vespakoen]

Hey hey!

I have been trying to make prebuilds of either node-iohook or the iohook package.
It's been rough so far =)

However, I at least got it to start compiling something, and producing actual compilation errors that hopefully lead us to a solution soon.

Here is the failing build: https://ci.appveyor.com/project/vespakoen/node-iohook/build/3/job/1l0gc19lrpw11vwj

And here are the relevant errors:

node-iohook.obj : error LNK2019: unresolved external symbol _hook_set_dispatch_proc referenced in function "public: virtual void __thiscall HookProcessWorker::Execute(class Nan::AsyncProgressWorkerBase<struct _uiohook_event>::ExecutionProgress const &)" (?Execute@HookProcessWorker@@UAEXABVExecutionProgress@?$AsyncProgressWorkerBase@U_uiohook_event@@@Nan@@@Z) [C:\projects\node-iohook\build\node-iohook.vcxproj]
node-iohook.obj : error LNK2019: unresolved external symbol _hook_run referenced in function "public: virtual void __thiscall HookProcessWorker::Execute(class Nan::AsyncProgressWorkerBase<struct _uiohook_event>::ExecutionProgress const &)" (?Execute@HookProcessWorker@@UAEXABVExecutionProgress@?$AsyncProgressWorkerBase@U_uiohook_event@@@Nan@@@Z) [C:\projects\node-iohook\build\node-iohook.vcxproj]
node-iohook.obj : error LNK2019: unresolved external symbol _hook_stop referenced in function "public: void __thiscall HookProcessWorker::Stop(void)" (?Stop@HookProcessWorker@@QAEXXZ) [C:\projects\node-iohook\build\node-iohook.vcxproj]

Compiling iohook with the settings in this pull, yields something like this: https://ci.appveyor.com/project/vespakoen/iohook/build/job/i06vnvm59na05k0d

I know I am getting closer, but this is literally the first time I am compiling C++ on Windows, so I don't really know what I am doing ;)

It would also be great if you can shed some light on the reason for there being 2 packages trying to achieve the same thing, I guess one of you simply didn't notice the other package was around?

I hope this helps!

Hi @vespakoen,
Sorry to let your PR without comment. if you can make it compiling on AppVeyor and Travis-CI I will merge it in prompt.

Please go a head and add necessary changes.
