Make all executables large address aware

[Laupetin]

Without setting the IMAGE_FILE_LARGE_ADDRESS_AWARE flag a 32bit application will only be able to allocate as much as 2GB memory (see also).

Since both Unlinker and Linker can load any amount of fastfiles beforehand, setting this option will increase the amount of possible loaded fastfiles by a lot.
It's not really an urgent issue but there should not be a downside to it really.
With premake this is probably done by using this: https://premake.github.io/docs/largeaddressaware/
