Modifies Helper.m, Helper.h, and VolumeSlider.m so when volume is limited to 100%, the volume slider is logarithmic with an X^2 approximation.
Also makes sure the value shown on the volume tooltip is not logarithmic when limited to 100%.
Makes some variables in VolumeSlider.m and parameters in Helper.h/Helper.m const as well.
Modifies the volume slider tooltip so that:
-If the volume slider falls below 10%, the volume tooltip will display one decimal digit of precision (e.g. 3.4%).
-Else if the volume slider falls below 1%, display one decimal digit of precision (e.g. 0.34%).
-Otherwise display the volume slider tooltip as normal.
This helps show changes in volume between 0% and 10% where a change in volume isn't shown in the UI but is heard (especially when the "Limit volume control to 100%" option is unchecked in the "Output" Preferences submenu.
