Rework design of user pages

[AndiPersti]

The design of the user pages (xxx's sentences, xxx's comments, ...) is very inconsistent:

• Some pages redirect to the all users page if given an unknown username, others display an error message. See Inconsistent behavior for links in sidebar menu on pages for an unknown user #2022
• Some pages show a user menu in the sidebar, others don't. See Poulpisator's comment on another issue
• If there are no contributions for a category (sentencs, comments, ...) some pages display the standard header with total count 0, others display a message that the user has not contributed any sentence, audio, ...
• Some URLs end with of/xxx, others end with of_user/xxx

FYI I've already started thinking about this and had plans to redesign those pages as part of the Responsive UI project. I don't have yet a definitive vision of how the user pages should be restructured though.

Perhaps you could have what is the sidebar now remain as a sidebar for people who use big screen computers, but have it wrap to below what's on the left on small mobile screens.

Something similar to how this page changes from a 3-column page to a 1-column page if you change the window size from computer-width to mobile-width.

That's the page we reach when searching for a member. But if there7s no activity to show, we get a blank page.
