Link journal entries to people

[jonasvp]

Currently the "Journal" and "Activities" are separate. That seems rather artificial - how about merging them and allowing journal entries to link one or more people to them?

And for extra credit: allow linking people using Markdown syntax from the journal entries, e.g.

I met [Mon](Monica Geller) on the street and talked to her about such-and-such. Then we met [Joey](Joey Tribbiani and the three of us had coffee.

This are as well two separate improvements. @djaiss would it be helpful if I open issues for issues which contain more than one change? IMO this would help to get a better overview of what was already requested.

@Nebucatnetzer Yes definitely. Ideally, one issue = one problem/bug/feature request, so it's easier to track. Thank you for your suggestions.

Journal entries are now created automatically when you create an activity.
