Install constdata.conf.
New command "list validations"
Additional validation-related tests.
Print validations and return values in info -v command.
Additional support functions.
Fixed error display.
Modularize using get_validations instead of calling API directly.
Fixed undefined value errors.
Fixed undefined value warnings.
Implemented interactive configuration mode.

Now the only mandatory parameter for the "define params" command is the
sketch name. If no file is given, the parameters will be queried
interactively. The interactive mode knows how to deal with scalars,
booleans, lists and arrays, and will do validation as values are
entered. If a sketch contains multiple bundles, it will also ask which
bundle to use.
do not call values on an array
