Kimth/view licks

@forea 
Minor tweaks to `view_behavior_with_licks`, namely:
- Use `set(CData,...)` rather than repeated `imshow` for performance reasons. See more <a href="http://www.mathworks.com/matlabcentral/answers/36698-imshow-in-gui-too-slow">here</a>.
- Border around the lickometer indicator -- to make it more visible when not triggered.
- Show frame count in title
