Rename QuickSortInPlace to TrueQuickSort or something similar.

It should be mentioned that QuickSortInPlace is the actual quick sort. Other implementation that allows using extra space is like quick sort but not the strictly the actual algorithm.

I've seen this at several places. For example the following implementation of quicksort in Haskell

quicksort :: (Ord a) => [a] -> [a]  
quicksort [] = []  
quicksort (x:xs) =   
    let smallerSorted = quicksort [a | a <- xs, a <= x]  
        biggerSorted = quicksort [a | a <- xs, a > x]  
    in  smallerSorted ++ [x] ++ biggerSorted  

It is shown as a quicksort implementation but in reality it is not.
A lot of newbies will get a wrong idea about the quicksort this way who are only learning algos this way.
It should at least be mentioned in the ReadMe that the one with the in-place is the real one.

Thank you for your issue @farkaskid
I've updated READMEs and mentioned your point there.
