#113 Allow change/add units for eval attributes displayed in taurusform

[marc]

Allow change/add units for eval attributes displayed in taurusform.

For the moment, using an eval expression does not display the units in a taurusform. For example if we do:
taurusform eval://{tango://sys/tg_test/1/short_scalar}
does not display the units even if tango://sys/tg_test/1/short_scalar has some unit defined.
This 'unit' problem in the 'taurusform' will probably be solved using Pint Quantities.

This should be addressed by the TEP14 (quantities support)

This is done in Taurus4

Units are correctly treated in evals that reference values with units.

Also, values with units can be created in Eval directly using "Q" or "Quantity":

taurusform 'eval:Q("1m")'
