Small fixes (#155)

* Fix various typos and references or links

- Misuse of product macro the x sign did not appear
- Use macro for milligrams
- Some refes were without hyperlink for some reason ?
- confusion between section and subsections
- a little grammar.. exact value not absolute, don't think a negative
  amount of flower was ever an option :D

* Use siunitx for temperature everywhere

Apparently some files escaped my script last time, or messed up in git
merge... Anyway fixed now and should be more consistent.

* Simplify Fermentolysis table

I woudl hope this is more clear with less lines.

* Remove double bottomrule

* Fix grammar

* Use correct font familly in preface

Small corrections on font familly and extra space for signature.
TODO: I did not change the paragraph breaking but we might want to
revisit it later.

* Fix wrong percentage range
