Ableitungsrechner v0.9-prealpha

• Added a GUI
• Added many comments to better understand the way the code works (and more are coming soon)
• Added fractions that need to be always written like this => (f(x))/(g(x)), f(x) and g(x) are mathematical terms, but they can't be fractions and g(x) can't be 0
• Added integer exponents for bracket terms => (2x+1)^2 or (2x+1)^-2 are now possible, but for fractions only positive exponents work, because inverse fractions don't work currently
• Fixed the multiple signs bug => 2+++---++2 is translated to 2-2
• Optimized a lot of code lines
• Improved derivative calculation
