Find GRPC & GRPC Linux Fixes (#101)

* Update enigma-dev submodule with latest CMake fixes that actually search for GRPC.
* Default GRPC to on for all platforms.
* Macro guard GRPC server plugin header in main window.
* Manually enter "127.0.0.1" for now since Linux GRPC has broken DNS currently which cannot resolve "localhost" address.
* Add test to check that `-nogrpc` flag works.
