Committed r1807487

I've added a unit test demonstrating this feature.
I agree this is definitely not an obvious syntax... nor very user friendly, as 
the 400.333F needs to be written F"1137191584".

> The format for specifying a float in the .config format is <key>=F"<float 
> value> and similarly for doubles but with the type character D.
> When the floats and doubles are encountered in the config, 
> java.lang.NumberFormatException is thrown with the message like:
> {code}
> java.lang.NumberFormatException: For input string: "400.333"
>       at 
> java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
>       at java.lang.Integer.parseInt(Integer.java:580)
>       at java.lang.Integer.parseInt(Integer.java:615)
> {code} 
> The code is actually parsing using Integer and Long classes!!
