Merge lp:~sam92/openlp/bug-1695620 into lp:openlp

[Samuel Mehrbrodt]

Make use of Mako for footer generation being configurable in song settings

- removed now obsolete and via template better configurable options to display "songbook", "written by" and "copyright" information in footer
- added explanation box for so far used settings as Mako placeholders
- added songs configuration setting for template including reset button
- added default template replacing currently existing configuration as best as possible (should be backwards compatible or at least be adaptable to correspond to former settings)
- write and adapt tests for new and removed functionality
- Added some more available fields in the footer: Alternate Title, CCLI Number, Topics, Authors (all music, all words)

You need to run CI on this to show the success of tests.
Not sure why but this request did a full download when I did a check out. Also cannot run due to chord issues.
Cannot run this but there seem to be lots of line breaks in the footer display. As the footer area is small this will not be displayed and lead to forum comments.
You need some validation do defend against too long footers!

[Raoul Snyman (raoul-snyman)]

We're moving away from Python generated HTML, and using a JS system based on Reveal.js. Come chat with tgc and myself in IRC.

review: Disapprove

> Cannot run this but there seem to be lots of line breaks in the footer display. As the footer area is small this will not be displayed and lead to forum comments.

The footer has the same height as before, there should be no difference by default.

So I replaced Pystache with Mako. Should be safe to merge now I think.
As the new renderer is in a very early state atm, I can't see how I can adopt this for the new renderer. Maybe we can merge this now and adopt when the new renderer is ready?

[Tim Bentley (trb143)]

Blank lines!
Will review tomorrow as I have bible study!
