- [def] is used to define a variable (like before)
but if we assign a string such as [def var "string"] the string is evaluated to bool
in a different way: empty string is false, not empty string is true
- added [def?] statement - similar like [def] but define a variable only if such
a variable is not already defined
- added [let] statement - similar like [def] but with lazy evaluation (it is an alias to a function)
if it is called to assign a string e.g. [let var "string"] then this has the
same meaning like [def] - an alias is only created when we assign a function e.g. [let var my_function]
both [def] and [let] are using the same Vars object
- added [let?] - make an alias but only if such a variable is not already defined
- a std::map of variables moved outside of Generator
added method void SetVariables(Vars & variables);
- fixed: a result status was not correctly propagated when evaluating [def] statements,
this was in Call(...) function: last_res from variables was set in Find()
but later was overwritten by Call(...) called for parameters (recursively)
in Pattern we have only the tree
in PatternParser there is the whole logic used to parse a file

added: ezc can use the logger from winix
added: we check how many [include] directive was called
(if more than 100 then we break - supposing infinite loop)
added: in Pattern we read from two directories
if a file is not in the first directory then we try to read
from the other one
