Feature Request: Debugging version of BeforeScript of template

[the-redback]

Hello,

Thanks for this great tool.

I use debugging macros with ifdef like following:

#ifdef  redback
#define bug printf("line=%d\n",__LINE__);
#define debug(args...) {cout<<":: "; dbg,args; cout<<endl;}
struct  debugger {template<typename T>debugger& operator , (const T& v) {cout << v << " "; return *this;}} dbg;
#else
#define bug
#define debug(args...)
#endif  //debugging macros

In this case -Dredback flag is provided with compilation command. Other people uses -DONLINE_JUDGE

Now, in my scenario, the following two command will be very useful,

$ cf test
$ cf test -d

-D flag is provided for debugging compilation in 2nd options.

To achieve this, one extra field debugging_before_script can be added to the templates.

{
  "template": [
    {
      "alias": "cpp",
      "lang": "54",
      "path": "...",
      "suffix": [
        "cpp"
      ],
      "before_script": "g++ $%full%$ -o $%file%$.o -std=c++17",
      "debugging_before_script": "g++ $%full%$ -o $%file%$.o -std=c++17 -Dredback",
      "script": "./$%file%$.o",
      "after_script": ""
    }
  ],
 }
}

If this sounds good, I can start working on the source code.
