I uploaded a new beta.

- degrees fixed (special category as it can be standalone or in 
combination).

- per fixed

- Hz, dB (actually deci + bel so megabel also works), lx, permille, t, 
k, Da added

- eV, m, \mu m, root added

- ad 1: should normally work out ok

- ad 2: no looking back (would demand an extra correction pass 
elsewhere, maybe some day)

- ad 3: see remark WS

- ad 4: see remark WS (also, the existing module was starting point)

- ad 5: depends on what users want

- ad 6: see remark WS

- ad 7: the old modules had that, maybe this one will have it too; in 
that case we need a list of descriptions too (for different languages) 
for units that make sense to be mentioned in such a list

- ad 8: manipulating the input this way is somewhat beyond the purpose 
of a typesetting system

- ad 9: much will be configureable; see mkiv file for an example of 
defining extra units (\registerunit [units] [point=pt, basepoint=bp]);

- I myself am not going to look in all kind of other tex stuff that lays 
around as it's up to users/usage what is added, given that it fits into 
the model of context; we have the old units modules as starting point
