Vs terminology in GUI

[Onur]

Hello,

This message is for the developer team ;)

I am just starting to use the engine. Thanks for this great project.

I noticed that there is a terminology conflict in the Site Conditions window of the GUI. 

First,  all "vs30" words should be written as "Vs30" ( the letter V must be uppercase).

In the two rows starting with "Minimum depth ...", these values are not Vs30 in my opinion. Because Vs30 is the average shear wave velocity (Vs) in the first 30 m of the soil, 1.0 and 2.5 km/s velocities at the deep part of the soil should not be called Vs30. Vs is the correct term. The two rows should be like this:

Minimum depth (m) at which Vs ≥ 1.0 km/s (z1.0) :
Minimum depth (km) at which Vs ≥ 2.5 km/s (z2.5) : 

On the other hand, in the mouse-over help labels, "... seismic waves ... " term shoud be " ... shear waves (Vs) ...". The term seismic wave contains all types of waves such as P, S, and surface.
