HID Project 2.4

A lot of changes were made to the official Arduino IDE. HoodLoader2 is now natively supported and pluggable USB and HID was introduced. Version 2.4 not only adapts those features, it adds even more functions compared to previous versions of HID Project. A lot of fixes and inner structures were made to accomplish this.

Different Keyboard layouts are not integrated into the current version since IDE 1.6.6 was released faster than expected. Other bugs might appear, feel free to report them.

HID Project 2.4 can now be downloaded via library manager. Older versions might appear as well but wont work (since at that time it was a whole core, not a library).
