We had a pattern where doubles were converted to long with
lrint() and then down-cast to a narrower int type.
Because this is unwieldy, introduce a function encapsulating
this.

The goal here is to add general addition and scalar multiplication
functions to the unit types.
Thereto, we need a CRTP
(https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern)
base class.
However, this breaks compound initialization, so we have to use
named initializers:
weight_t { 2000 } -> weight_t { .grams = 2000 }
The good thing is that this is exactly how these classes were
supposed to be used: make the unit explicit!

D7 232 Bar tank added in line 342.
D7 232 Bar are common in Europe, not just D7 300 Bar.

Also, turn it to use std::string instead of writing into a
global(!) buffer. This was not reentrant.

Feels natural in a C++ code base.
The commit is somewhat complex, because it also changes the
return type to volume_t. The units system really needs some
work. :(

In analogy to other tables, this creates a struct that derives
from std::vector<>. This is generally frowned upon, but it works
and is the pragmatic thing for now. If someone wants to "fix" that,
they may just do it.

This one-liner wasn't really doing anything and there was only
one user of the return value.

The important point is that this now takes a reference that
avoid string copying. The old code used C-strings and therefore
copy-semantics were OK.

This is a messy commit, because the "qPref" system relies
heavily on QString, which means lots of conversions between
the two worlds. Ultimately, I plan to base the preferences
system on std::string and only convert to QString when
pushing through Qt's property system or when writing into
Qt's settings.

This is a humongous commit, because it touches all parts of the
code. It removes the last user of our horrible TABLE macros, which
simulate std::vector<> in a very clumsy way.

This had to be done simultaneously, because the table macros
do not work properly with C++ objects.

Makes the code much nicer to read.
Default initialize cylinder_t to the empty cylinder.
This produces lots of warnings, because most structure are now
not PODs anymore and shouldn't be erased using memset().
These memset()s will be removed one-by-one and replaced by
proper constructors.
The whole ordeal made it necessary to add a constructor to
struct event. To simplify things the whole optimization of
the variable-size event names was removed. In upcoming commits
this will be replaced by std::string anyway.

Use std::vector<> instead of fixed size array.
Doesn't do any logic change, even though the back-translation
logic is ominous.
