First version of PhDebug

Working with function name
Now with timestamp (not fully functionnal - see description)

Display even if it shouldn't :
if (false)
    DEBUG << "Hello";
will display something
minor changes in main
step one with singleton - not working
Might found the solution - check @
Add filter for Date/Time - not working with function name
Now supports function name filter
