WARNING: GetKeyPressed() <-> GetCharPressed() #1336

Browse Source 
Previous GetKeyPressed() method was actually returning unicode codepoints equivalent values instead of the key-code of the pressed key. So, it has been replaced by GetCharPressed(), returning unicode codepoints and GetKeyPressed() now returns key-codes.
