Build a D project is now easy

[bioinfornatics]

thanks nick

i have pushed a fix for dmake and in same time for ddbi

i think they are a little bug easy to fix when you set a lib do not put at the end '/' character
example: dmake -p src -l src/dbi instead  dmake -p src -l src/dbi/

To do change all path string and array Path string to Path object

if someone could do this i think i can't do this before 1 week
