Because it produces warnings on some versions of Perl.

- CONF_ERR type removed
- fault encoding via 2 bits

- minor bug slipped in when introducing the cloning the existing settings
- add support for the 'depends_on' property of FIJI constants

This allows to present the user with a meaningful message in the main window.

 - get rid of separate ARM and INJECT DURATION widths
 - allow for different external and internal representation of values
 - highlight invalid user entries
 - validation of settings depends on tool flow phase (e.g. setup)

LFSR button was permanently disabled until RUNTIME or STUCK_OPEN after PASS_THRU selected in model_menu
Is now also enabled for other fault models

Fixes saving of design constants again.

 - Always save it.
 - Having no FIUs in a config file is no longer an error
 -

Also,
 - no longer support FIU_CFG_BITS from .ini file,
 - rename injection to inject (about everywhere).

The 'optional' attribute of function parameters is documented but not implemented?!
