Fixing tons of bugs.

1. Height of object list items should be adaptable to image's heights.
2. Fixed object positioning
3. Buttons of object rows are now vertically centered.
4. Fixing expr-eval not recognizing certain characters as part of the variable.
5. Fixing silent error when misentering variables preventing you from changing the expression again.
6. Fixing points in gains and phases having name-related issues.
7. (in the previous commit) Fixing invisible buttons at the end of the object row when not changing tabs.
