New release v0.5 of the D bindings for SAP NetWeaver RFC SDK

[Kai Nacke]

Hi!

I made a new release of sapnwrfc-d, the D bindings for the SAP 
NetWeaver RFC SDK.

Included are the following changes:

   - New bindings for basic decimal arithmetic (sapdecf.h)
   - A lot of fixes to the bindings and new, automatically 
generated bindings
   - New example applications
     computeday: This is an example of a simple RFC call
     repotool: This utility displays the metadata for a RFC

The included set of example applications show how easy it is to 
call an RFC. To use the library just add a dependency to your 
dub.json/dub.sdl file or clone the source at 
https://github.com/redstar/sapnwrfc-d.

Regards,
Kai
