improve phonon

[superstar54]

• boundary atoms do not move in phonon
• make it more smooth, inside one second more frame, allow the user to control it.

      // control the speed of the animation
      editor.avr.frameDuration = 20;

• not break bond

editor.avr.bondManager.hideLongBonds = false;

• provide option to hide the cell

        editor.avr.showCell = false;

• provide option to hide the vector

editor.avr.VFManager.show=false;

• disable isosurface gui

• bug: download in full screen shows nothing.

• phonon movement is different, rotation?

• PbI2 bonds do not show, maybe increase the bond cutoff?

I'll record here issues I'm seeing as you develop:

• Vectors stop updating when you change anything in the WEAS control panel
• The size of the cell is somehow tied to the size of the containing div and is affected by window resize
• Rotations don't seem to work. The vibrational mode appears different from the old app
