[C/ASM] Easy to use DLL hijacking examples

x64 dll hijacker made using this might cause errors on some Windows flavours & build configs due to wrong stack alignment in the "PRX_EXPORT64 macro procname:req, ordinal:req" defined in each asm file, causing a #GP fault on instructions needing 16 byte boundary (movaps), it happened some dozen chained calls from the unaligned stack place, in system area.

Fix:
alloc_stack 20h to alloc_stack 28h
....
add rsp, 20h to add rsp, 28h
in the macro function definition of the asm file

Thanks, I have committed the changes you suggested. I don't have time to test it, but I'm sure it works fine.

Just fyi, I haven't been maintaining these templates recently, because I switched to using __pfnDliNotifyHook2 to implement DLL proxying on my personal projects, and haven't had time to create new templates for all the DLLs supported by this project.
