Scon Demo file Improvements

Created by: Protofall

This depends on #25 (closed) , once that's done part of the demo scons file's functionality will be moved to an external file (Located in the lib folder). There will be 3 sorts of functions

• Input handling, takes input, returns list of platforms and debug-ness. If an error occured it doex exit(1) in the function
• Env creation. Takes debug and platform list to return a list of environments and platforms. Also you can optionally give it some extra CCFLAGS and libraries...maybe
• The for loop that builds the stuff. Not sure how possible this one will be to do.

The first one could be done by a non-scons specific function, second would use a function with scons functionality and the last one might need an sconscript? idk

Oh, also make program name = to scons file's host folder
