Ref email, some small UI fixes

[cfsamson]

Hi. Making a PR here as mentioned in the email. Now this was originally written in typescript, but I just rewrote it to fit in the form and style as the original HotTowel template. There are three small changes:

• Menuitems now show after going from large screen to small screen, clicking a menuitem and then going back to large screen
• When clicking on a menuitem on small screen, the menu closes after click. I used a seperate directive for this, as it is a bit tricky due to the ng-repeat. There probably is a way to do it in i.e. the sidebar directive, but I haven't figured out any other way to do it.
• The dissolve animation now works as in the original example

It looks like there are changes to ccImgPerson but it is the same, don't know why it shows as change in the diff.

Let me know if there if you have any comments :)
