Improvement: Add Timeline visualisation to tournament create/edit/view

[M4LuZ]

Expected Behavior

It would be nice to use the visual representation of the tournament timeline also during creation / editing of a tournament to see how match length and breaks influence runtime.
It would also be good to have a user-specific timeline with all (potentially upcoming matches (based on current state + assumption that all games are won) plus a tabular listing with all upcoming matches for a person.

Current Behavior

Timeline is static and only shown in general overview.
Adding/editing Tournaments does not provide a direct feedback how long the tournament will take and what the timing is

Possible Solution

Make timeline / bargraph generic function, implement functionality where needed

Context

Not sure how I came up with this. Thought just appeared ;)
