The calculator/2d menu/3d menu was wasting so much space, and didn't look good.
The menus are now organized in two: settings and file.
File has the options save, and loading options, also,
The save shortcut triggers the calculator save log, save 2d or save 3d based on in which tab you are (calculator, 2D or 3D)
This also applies now for the reset view, that reset the currently selected tab.
Removed the 'clear calculator' option from the menu and moved it to it's own space inside of a Layout
