[Development] QtCon session notes

[Edward Welbourne]

> Also put the notes to the Wiki https://wiki.qt.io/Qt_contributors_summit_2016

Suggestion: let's use the features of the tool to do the work.  Add
[[Category:QtCS2016]] to any pages related to this, and we can just turn
the page above into the category over-view page (with a redirect,
naturally).  That way, you just have to set the category on your page,
you don't have to also edit the page that needs to link to it.

Use the strengths of the tool to our advantage ...
