WIP: Schedule

[shaib]

This, for now, includes the skeleton of the agenda, and fixes the symposion/schedule app to work with Python 3.

The schedule is available at the /schedule url (it is not bi-lingual, at least yet), which is not linked from the main page. With the PR in its current state, it is just a skeleton. Note that the page generated uses a HTML <table> -- but AFAICT it is responsive enough this way.

We still need to review/fix the schedule editing views, even assuming this is all well, and also verify that the presentation works well when there is content.

p.s. my version of this branch is at https://github.com/AmitAronovitch/pycon-israel/tree/schedule-fixes for now they do not diverge much

@shaib The modal is not correct, the diff for _slot_edit.html:

Thank you so much

PR updated with @MeirKriheli's fix of the template and adding the schedule to the navbar. The schedule is added only for logged-in users for now.

Not pushing because late at night, but this should be good to go.
