Dimm start button when depressed

[dzid26]

Tiny issue.

I have delay before acquisition starts. I found myself clicking the button multiple times because of delayed reaction.

Use different colors for the button active to give instant feedback that the button is depressed.

 ImGui::PushStyleColor(ImGuiCol_Button, color); 
 ImGui::PushStyleColor(ImGuiCol_ButtonHovered, color); 
 ImGui::PushStyleColor(ImGuiCol_ButtonActive, color);
