Fix duplicate flowchart (#222)

* Fix duplicate flowchart

This combines both flowcharts into one

* Start on pink for starter readiness flowchart

* Add braces to TikZ flowcharts

* Rewired flowchart with right-angled transitions

* Change Arrows from right-angled to star connected

As I could not really find a way not to have diagonal arrows... I
decided to embrace it instead.  YMMV

* Homogenize box sizes

* Align on unit inside the flowchart node

* Fix code typo in starter readiness flowchart

* Create a MWE showing (known) ebook issues

Those issues are:
- Temp in flowchart
- No front image
- Chemical formula
- No list of flowcharts
- Weird looking table

Also test fonts, accents, etc.. seems ok.

* Make ebook the default target

* Revert "Create a MWE showing (known) ebook issues"

This reverts commit dac7f8f21d.

* Revert "Make ebook the default target"

This reverts commit e92e464459.
