now it's possible! printing floating point numbers at compile-time

[Stefan Koch]

Hi Guys,

during my research on floating point numbers I came across a 
short and efficient implementation[0] of the grisu2 algorithm for 
converting floating point numbers into strings.

Which I then ported into CTFEable D code.
Thus enabling you to convert doubles into strings at compiletime.

Cheers

Stefan Koch

P.S. You can find it at my fork of fpconv[1].
