Additional debugging input from parser
Raise typed exceptions in text parser
More rigid matching of bool, class and property

Existing code was too lenient in matching piped regexps:

1) no word boundaries mean that, for instance, an invalid value such as "kindergarten" actually matches as "kind"

2) the matcher would not refuse multiple valid options separated with pipes (it would for instance match "true|false" as a valid boolean value)
Action parsing specs, incl. negative workflows
