Multithreaded Buffered Reader

[Enn3Developer]

Implement, in a way or the other, a file reader that loads the content in a buffer and does so in another thread The goal is to parallelize the code analyzer and the file reading to gain something with the performance (this change should be visible with larger files) Prob this should be for 3.1 but can later be changed to 3.X or even 4.0 in case it misses the feature window
