[BUG] GUI translates all atoms instead of the unit cell itself

[Torilla]

Describe the bug When modifying periodic structures, I often toggle between selecting, modifying mode and camera mode using the keyboard shortcuts. However, sometimes when you switch back from modifying to camera and try to rotate / translate the whole view, the atoms are moved inside the unit cell instead, which f**s up everything you did before :smile:

To Reproduce Not 100% sure what exactly triggers the bug, but I am fairly certain that it is connected to using the hotkeys instead of the dropdown menu.

Expected behavior Well,...

Your system/installation:

• Vipster v1.19.1b (I have observed this in previous versions as well, just haven't filed a bug report yet)
• OpenGL Renderer: AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.12.11-300.fc34.x86_64, LLVM 12.0.0)
• OpenGL Version: 4.6 (Core Profile) Mesa 21.1.3
• Linux Fedora

Sorry for being silent about this issue. I still could not reproduce this, could you provide a specific way to reproduce this?
