Update of Visual Studio gitignore file.

TeX: feynMF/feynMP

add the *.VC.db to unreal engine ignore

as of visual studio 2015 update 2 this file stores the intellisense database.
this file is typically huge and shouldn't be included in a repository.

If the .gitignore file is inlcuded in another project, it may be feasible to have a reference to origin.
